Abstract:It is most significant to achieve environment protection in construction industry for which prefabrication construction technique is considered to be most efficient sustainable construction method. The importance of prefabrication is based on the influence of different activities elaborate such a waste management, adaptation of material reuses and recycles. This research paper includes a dynamic design approach to evaluate the cost performance of construction project using prefabrication construction method along with applying the subsequent waste treatment activities to accomplish waste management. The construction cost of duplex villathrough traditional construction has been carried out. The construction cost of the same project has then been calculated by the present prefabricated assembly market prices. After critical comparison between construction costs of traditional and prefabrication methods, a significant cost saving has been noticed. The day by day increasing public awareness about the environmental impacts of construction waste has been resulted in including waste management as a major function of construction project management by some construction organizations. Although, some of methods have been developed for construction waste management it is still of much importance that no research has been done so far in this topic to introduce waste minimization through necessary waste treatment activities. This research paper emphasis on the identification of supreme horizons of prefabrication techniques and methods in construction industry by converging on the aggressive need of suitable training and skills for workplace.

This document evaluates a study case of a sustainable commercial building called "30 The Bond" in Sydney, Australia. It achieved a high performance and low energy consumption through designing for occupants with sustainable criteria and an adequate site analysis. The site had constraints like only three exposed facades and an historic sandstone wall on the fourth facade. This wall provided thermal mass and was incorporated into the building design. An external shading system and double facade with intelligent controls were used to reduce energy consumption while improving indoor comfort and performance, considering the site's sun exposure, winds, and urban context. Through its design strategies, 30 The Bond achieved a 5-star energy rating from the Green Building Council of Australia's rating tool.

There are various categories of materials including metals, ceramics, polymers, semiconductors, and composites. The structure of materials profoundly influences their properties. Understanding this relationship allows controlling materials properties through synthesis and processing.
A strategic framework for sustainable construction in jordanAlexander Decker
This document discusses sustainable construction in Jordan and proposes a strategic framework. It argues that sustainable construction in Jordan has focused too narrowly on technical issues like energy efficiency, while ignoring important social and cultural factors. A more holistic approach is needed that considers things like water access, sanitation, social issues and local context. The challenges of developing countries mean sustainable development interventions must address both development needs and environmental protection principles. The limitations of current green building approaches in Jordan are outlined, and it is proposed that a strategic framework is required to guide more sustainable construction that integrates socio-cultural dimensions.

Housing and climate change in the nigerian built environmentAlexander Decker
This document summarizes a journal article about the relationship between housing, climate change, and the built environment in Nigeria. It finds that climate change is caused by both natural forces and human activities like building houses, which alters the natural ecosystem balance. Housing construction and energy use in homes produces greenhouse gas emissions that contribute to global warming and climate change. The document recommends adopting adaptation and mitigation strategies through sustainable architecture to reduce these impacts while allowing for human development and resource use.
Climate change and architectural practice in nigeriaAlexander Decker
Climate change is impacting architectural practice in Nigeria. It is affecting building design and architects must design sustainable buildings that can adapt to changing needs over time. As the climate changes and its effects cannot be eliminated, architects and other industry professionals must produce buildings that can withstand climate impacts and reduce vulnerability. Responding requires both mitigating further climate change and adapting to current and expected future impacts through improved building design.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Afghanistan has suffered from four decades of war, causing a massive migration of the rural population to the cities. Kabul was originally designed for 1,5 million people, whereas there are now 5 million in the city. The importation of modern western styles housing for rapid reconstruction reveals apparent cultural conflict and a significant environmental footprint. The new drive for sustainable reconstruction should consider the use of local materials combined with modern technologies. Earthen architecture underlies the embodiment of Afghan architecture. This research aims to revisit traditional Afghan earthen construction with the tools of industrial modernity. The three soils of the Kabul region are first characterized. Sun-dried mud brick and compressive earth block, with and without stabilization have been prepared and tested in the laboratory to develop the most suitable earth construction element which is cost-effective and easily available compared to imported modern products.

REPAIR, REHABILITATION &RETROFITTING OF RCC FOR SUSTAINABLE DEVELOPMENT WITH ...civej
The construction material mainly reinforced concrete is being used extensively for various types of
construction projects. However, the deterioration of Reinforced Concrete structures is recognized as a
major problem worldwide. Apart from requiring regular maintenance, many structures require extensive
Repair, Rehabilitation &Retrofitting. Over a period of time, as these structures become older, we find in
them certain degradation or deterioration with resultant distress manifested in the form of cracking,
splitting, delaminating, corrosion etc. Such deteriorated structures can be rehabilitated and retrofitted by
using various types of admixtures & modern repair materials. The paper brings out the present state of
concrete structures & the major areas where improvement is needed during its service life stage for
sustainable development & also the method of carrying out Repair, Rehabilitation &Retrofitting.This has
been brought in details in the paper along with Case studies, where the Author of the paper was directly
involved in planning and execution of the jobs.

Toward green concrete for better sustainable environmenthsaam hsaam
This document discusses efforts to develop green concrete as a more sustainable building material. It begins by noting that cement production currently accounts for 8-10% of global CO2 emissions. The document then discusses various approaches researchers have taken to reduce the environmental impacts of concrete, including substituting fly ash for cement, using recycled materials, and nanoengineering cement mixtures to improve performance. It emphasizes that green concrete must use waste materials, have a sustainable production process, and perform well over its lifetime. The document surveys cleaner cement production technologies and argues green concrete can help all three pillars of sustainability.
Construction projects involve many complexities. Proper project planning and management are important to control costs, schedule, and quality. Contract types like lump sum contracts can help allocate risks between owners and contractors. New technologies and techniques can improve efficiency in areas like planning, materials management, and construction practices. Achieving greater efficiency through initiatives like improved planning, use of new technologies, listening to staff, and managing client expectations can help complete projects under budget and on schedule while generating more profits.
Construction materials play a crucial role in modern infrastructure projects by providing strength, durability, and ensuring structural integrity. Some key construction materials discussed include concrete, widely used for its compressive strength; asphalt, used in road construction; and cement, an essential binder that increases load-bearing capacity. Proper selection of construction materials considers technical requirements, environmental conditions, and cost to balance quality with sustainability and affordability. These materials are critical components for building safe and long-lasting structures.
Sustainability through Intelligence in BuildingsIJERA Editor
Energy efficiency and energy preservation are two primary worldwide concerns in current reality. Thus, sustainability encompasses those two issues, giving that as a general term refers to the capacity to endure. In architecture sustainability describes environmentally conscious design techniques, minimizing negative environmental impact and enhancing efficiency in the use of materials, energy and space. In every level of design and construction of a building, environmental issues should be taken into account. Each specific decision and choice may have consequences for the environment. Sustainability through the proper and sound use of materials is an obvious practice. Beyond that, intelligence integrated in buildings can promote energy efficiency and wider life cycle. After a brief clarification of what intelligence in buildings entitles, a series of case studies are presented in order to support the fact that in deed energy efficiency and energy preservation (in some cases energy production as well) are achieved through the use of intelligent systems in structures.
Study of Effect of Nano materials as Cement Replacement on Physical Propertie...IRJET Journal
This document summarizes research on the use of nanomaterials like nano alumina, nano titanium dioxide, nano zinc oxide, and nano-silica as cement replacements in concrete. It discusses how these nanomaterials can improve the physical properties and durability of concrete, but that their use is currently limited due to lack of awareness and high costs. The document reviews several studies that found these nanomaterials can increase concrete's strength, workability, and decrease permeability when used to partially replace cement. However, for wider implementation, issues like health effects and cost competitiveness need further research.

Effect of Steel Slag as Partial Replacement of Cement on Property of Concreteijtsrd
A well maintained infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements is challenging. Concrete as a construction material is in use for several decades. Concrete can withstand the severest environments and engineers are constantly trying to improve its performance with the aid of modern admixtures and waste materials with or without cementious properties. The use of waste material in concrete helps to consume these waste materials and also improves the properties of concrete in fresh and hydrated states.Civil structures are designed considering the target compressive strength of the concrete. Although, few other parameters such as workability, water to cement ratio, setting time of cement and surface hardness influence the performance of concrete.In the present research a series of experiments had been performed to compare the use of Steel Slag as partial replacement of cement in different proportions. Concrete mixes are modified by 5 10 , 15 , 20 and 25 of Steel Slag as replacement of cement.The main conclusions drawn are inclusion of Steel Slag increases the compressive strength up to a certain proportion and then reduces the strength. Steel powder increases the strength but reduces the workability. Comparatively higher early strength gain 3 days, 14 days, 28 days is obtained with Steel Slag concrete.

It emphasizes that green concrete must use waste materials, have a sustainable production process, and perform well over its lifetime. The document surveys cleaner cement production technologies and argues green concrete can help all three pillars of sustainability.
Construction projects involve many complexities. Proper project planning and management are important to control costs, schedule, and quality. Contract types like lump sum contracts can help allocate risks between owners and contractors. New technologies and techniques can improve efficiency in areas like planning, materials management, and construction practices. Achieving greater efficiency through initiatives like improved planning, use of new technologies, listening to staff, and managing client expectations can help complete projects under budget and on schedule while generating more profits.
Construction materials play a crucial role in modern infrastructure projects by providing strength, durability, and ensuring structural integrity. Some key construction materials discussed include concrete, widely used for its compressive strength; asphalt, used in road construction; and cement, an essential binder that increases load-bearing capacity. Proper selection of construction materials considers technical requirements, environmental conditions, and cost to balance quality with sustainability and affordability. These materials are critical components for building safe and long-lasting structures.
Sustainability through Intelligence in BuildingsIJERA Editor
Energy efficiency and energy preservation are two primary worldwide concerns in current reality. Thus, sustainability encompasses those two issues, giving that as a general term refers to the capacity to endure. In architecture sustainability describes environmentally conscious design techniques, minimizing negative environmental impact and enhancing efficiency in the use of materials, energy and space. In every level of design and construction of a building, environmental issues should be taken into account. Each specific decision and choice may have consequences for the environment. Sustainability through the proper and sound use of materials is an obvious practice. Beyond that, intelligence integrated in buildings can promote energy efficiency and wider life cycle. After a brief clarification of what intelligence in buildings entitles, a series of case studies are presented in order to support the fact that in deed energy efficiency and energy preservation (in some cases energy production as well) are achieved through the use of intelligent systems in structures.
Study of Effect of Nano materials as Cement Replacement on Physical Propertie...IRJET Journal
This document summarizes research on the use of nanomaterials like nano alumina, nano titanium dioxide, nano zinc oxide, and nano-silica as cement replacements in concrete. It discusses how these nanomaterials can improve the physical properties and durability of concrete, but that their use is currently limited due to lack of awareness and high costs. The document reviews several studies that found these nanomaterials can increase concrete's strength, workability, and decrease permeability when used to partially replace cement. However, for wider implementation, issues like health effects and cost competitiveness need further research.

Effect of Steel Slag as Partial Replacement of Cement on Property of Concreteijtsrd
A well maintained infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements is challenging. Concrete as a construction material is in use for several decades. Concrete can withstand the severest environments and engineers are constantly trying to improve its performance with the aid of modern admixtures and waste materials with or without cementious properties. The use of waste material in concrete helps to consume these waste materials and also improves the properties of concrete in fresh and hydrated states.Civil structures are designed considering the target compressive strength of the concrete. Although, few other parameters such as workability, water to cement ratio, setting time of cement and surface hardness influence the performance of concrete.In the present research a series of experiments had been performed to compare the use of Steel Slag as partial replacement of cement in different proportions. Concrete mixes are modified by 5 10 , 15 , 20 and 25 of Steel Slag as replacement of cement.The main conclusions drawn are inclusion of Steel Slag increases the compressive strength up to a certain proportion and then reduces the strength. Steel powder increases the strength but reduces the workability. Comparatively higher early strength gain 3 days, 14 days, 28 days is obtained with Steel Slag concrete.

Transparent concrete as an eco-friendly material for buildinginventionjournals
Engineers have now developed concrete mixtures that are capable of transmitting light. By switching the ingredients of traditional concrete with transparent ones, or embedding fibre optics, translucent concrete has become a reality. Light Transmitting concrete, also known as translucent concrete. The main purpose was to use sunlight as a light source in order to reduce the power consumption of illumination. Translucent concrete is a concrete based material with light-transmissive properties, obtained due to embedded light optical elements like Optical fibres in it. Light is conducted through the stone from one end to the other. Translucent concrete is also used in the smart construction. Therefore the fibres have to go through the whole object. Transparent concrete is also known as the translucent concrete and light transmitting concrete because of its properties. It is used in fine architecture as a facade material and for cladding of interior walls. Light transmitting concrete is one of the fibre reinforced concrete which is used for aesthetic application by incorporating the optical fibres in concrete. Optical fibres are one which helps for transmission of light through fibre. The end-lite type of fibre is used to increase the aesthetic appearance of the concrete. The concept of light transmitting concrete is like a transparent concrete. When it is used in ceiling or side wall, it is exposed to direct sun light which transmit the image but not completely transparent. In this paper the smart translucent concrete can be regarded as a green energy saving construction material. It is a promising technology for field applications in civil Infrastructure.
Han Wu is proposing a project to manufacture concrete canoes. Through experimenting with concrete mixtures, Wu aims to create lightweight yet strong concrete that can be molded into various shapes. The goal is to challenge preconceptions of concrete as always being heavy, and to develop more affordable canoe construction methods, especially for areas lacking iron. Wu will experiment with concrete ratios to achieve the right properties and possibly elastic behavior. If successful, the concrete canoes could be decorated and used in applications where traditional materials cannot be used.

This document provides a state-of-the-art review on concrete made with recycled waste PET as a fine aggregate. It discusses how PET waste is a growing problem and recycling it by using it in concrete has benefits like reducing waste and natural resource consumption. The review summarizes several studies that investigated how replacing fine aggregates in concrete with PET waste affected fresh concrete properties like workability and density, as well as hardened concrete properties like compressive and splitting tensile strengths. Most studies found that workability decreased as the amount of PET increased due to its irregular shape, while density also generally decreased, making the concrete lighter. The properties varied depending on the type and shape of the PET used. Overall, the review indicated that PET showed potential
This document provides a state-of-the-art review on using recycled waste PET as a fine aggregate in concrete. It discusses how plastic waste like PET is a growing problem and recycling it can help address sustainability issues. Previous studies have shown PET can partially replace natural aggregates in concrete due to its properties. The review summarizes research on how PET replacement affects the fresh and hardened properties of concrete, like workability, density, compressive strength and splitting tensile strength. Most studies found that workability decreases but strength is maintained at low PET replacement ratios of up to 20%. The review aims to evaluate the suitability of PET as a concrete aggregate and the potential advantages it provides to sustainable construction.
This document discusses future directions for research on nonconventional and vernacular construction materials. It begins by defining conventional materials as those with widespread use, industrial processing, and low costs, while nonconventional materials are used for cultural, environmental, or technological benefits. The document advocates for a "sustainable-scale" approach that combines the attributes of nonconventional materials with the scale of conventional materials. It then discusses using life cycle analysis to evaluate materials and assess their potential for sustainable scale based on environmental impacts, costs, and other factors across the entire supply chain and lifecycle. The document provides an example comparing the embodied energy of coir binderless board, fiberglass, and mineral wool insulation materials.
Ultra-high-performance fiber-reinforced concrete. Part II Hydration and micro...Shakerqaidi
This document summarizes a review article on ultra-high-performance fiber-reinforced concrete (UHPFRC). It discusses UHPFRC's hydration, microstructure, advantages, and disadvantages. Regarding hydration and microstructure: Cement hydrates similarly to traditional concrete but produces a denser matrix due to lower water content and finer supplementary cementitious materials. Increased curing temperature hastens hydration. The microstructure is highly dense and compact, with a tight fiber-matrix interface. Hydration products like calcium silicate hydrate contribute to a thick microstructure. The review aims to advance understanding of UHPFRC to promote further research and applications.
Behavior of Concrete Using Copper Slag As A Strength Parameter in Low Cost Co...ijtsrd
The value of concrete in present society cannot be underestimated. We can see concrete structures everywhere, such as buildings, roads, bridges, and dams. There is no escaping the impact concrete makes on your everyday life. Concrete is a composite material which is made up of filler and a binder. Typical concrete is a mixture of fine aggregate sand , coarse aggregate rock , cement, and water. Cement and lime are usually used as binding materials, while the sand binder is mixed as fine aggregates and crushed stones, gravel, broken bricks clinker is employed as coarse aggregates. The concrete having cement, sand and coarse aggregates mix up in an appropriate percentage in addition to water is called cement concrete. In this kind of concrete, cement is used as a binding substance, sand as fine aggregates and gravel, crushed stones as coarse aggregates.An investigation relating to the use of byproducts to enhance the functions of concrete has been about for many years. In the recent years, the researchers have been made to use industry by products such as fly ash, silica fume, ground granulated blast furnace slag, glass cullet, etc., in concrete production and civil applications. The potential uses of industrial byproducts in concrete or as a partial aggregate substitution or as a partial cement substitution depending on their chemical composition and grain size, The utilization of these materials in concrete comes from the environmental constraints in the safe disposal of these products. Big interest is being focused on the environment and safeguarding of natural resources and recycling of waste materials. Various industries are producing a significant number of products which incorporate residues such as reclaimed aggregates, reclaimed asphalt pavement, foundry sand, copper slag, fly ash, glass cullet, polyethylene terephthalate, high density polyethylene HDPE , unplasticized polyvinyl chloride UPVC , plasticized polyvinyl chloride PPVC , low density polyethylene LDPE , polypropylene PP , polystyrene PS , expanded polystyrene UPS .

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Transportation has always been the backbone of development. Transit-oriented development (TOD) has been theorized, piloted and expanded increasingly in the past few decades. In this regard, this paper investigates the relationship between urban development, the transportation process, and the required implementation guidelines within fast-urbanizing cities, such as Cairo. After reviewing different related sustainable development theories, the study investigates pioneering case studies that have applied TOD and provided adequate implementation frameworks. The authors then extract and compare a set of required policies. The current Egyptian development paradigm is then discussed in relation to these enabling policies, focusing on Greater Cairo Region, Egypt. The authors debate previous development plans, progress, and newly proposed ones, focusing on the transportation process as the means for development. The study concludes with a set of required guidelines to ensure the integration of transportation with land-use planning, thus ensuring a more prosperous and inclusive urban development.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
This study investigates how urban parks can contribute to helping cities become more sustainable through developing a set of criteria for the sustainable design of urban parks. Today, there is no example around the world where all the proposed sustainable design criteria are applied together in a specific urban park. In this context, this study aims to make a novel contribution by systematically reviewing the literature on the sustainable design of urban parks. In the light of research findings, this study contributes to the implementation of a comprehensive sustainable park design practice in our cities in the future. These design criteria may further serve as performance indicators to offer information and know-how to local authorities, practitioners, communities, and other actors in this field to help them assess their success levels and progress over time.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Rehabilitation projects are interventions that can lead to the transformation of the socio-spatial structure of obsolescent neighborhoods. The main intention of such projects is the creation and/or improvement of social interactions after physical and functional interventions. Urban Renewal Organization of Tehran (UROT) is tasked with identification of target obsolescent neighborhoods, preparation of neighborhood development plans and implementation of rehabilitation projects to improve the quality of space and stimulate social interactions. In this paper, three urban spaces in different scales (“micro” for neighborhoods, “meso” for local and “macro” for trans-local scales), designed and implemented by UROT, were selected as a case study. By designing and filling a questionnaire and after analyzing research findings, the effect of the scale of the urban project on different activities was evaluated based on the Gehl model. Overall, in the expanded model based on the scale of space, an inverse ratio between the scale of space and both optional selective and social activities has been revealed.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The COVID-19 lockdown period has highlighted the ability of housing to accommodate a comprehensive programme typical of the city and its public space. Housing units of under 60 m2 and in blocks of flats are the more vulnerable, as they have a higher percentage of non-community open spaces. That problem was analysed using a methodology based on psychological, urban planning and architectural indicators applied to two coastal cities in the Mediterranean area of southern Spain. The results highlight three aspects in this type of dwelling: the need to consider the orientation of the housing to improve the quality of indoor and outdoor space; the need in public housing policies for a greater number of rooms to facilitate remote working; and finally, the importance of functional terraces overlooking green areas.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Recently the effect of greenhouse gases (GHGs) is worldwide terrified anxiety to the public and scholars. Even this global problem is one of the great issues that continuously makes worrying the governments and environmentalists, but its solution findings are not out of the image at all. In this study, we have proposed and analysed a mathematical model for the solvable management of GHGs by sowing the seeds of green building dynamic systems. Moreover, in the model, the human community is used to enhance the production power of individuals of green buildings by absorbing the GHGs. The model is analysed by stability analysis at the equilibrium points: trivial and global equilibrium, and also by convincing the stability and instability of the system of equations. The behaviour of the propound model has been developed by numerical simulations which shows the rate of the fruitfulness of GHG components.

Tourism is a major economic source for Egypt, due to its significant natural and cultural attractions. Yet, rapid development and construction of touristic facilities have a negative impact on the fragile natural and cultural heritage. This paper studies the recent touristic developments of the coastal stretch of Ain-Sukhna on the Red Sea coastal region of Galala Mountain, and their impact on the surrounding natural and cultural attractions. Coral reefs and rich marine life have made this stretch among the prime fishing and scuba diving destinations in the world. The area is also famous for its year-round sunny beaches and the spectacular coastal scenic drive where Galala Mountain reaches the Red Sea. Recently, development has started on the mountains following the construction of Galala Mountain Road. Galala City started with Galala University and several residential, touristic, and commercial facilities. This paper studies the pattern of development in the area during the past 40 years and assesses its impact on natural and cultural resources.

ABSTRACT
Heritage admits diverse readings depending on different territorial spaces, contexts, and knowledge fields. The relation between Heritage and the social contexts is one of these knowledge areas. But Heritage accepts a dual perception as a cultural reflection. It may be considered either as the origins of the conflicts or the engine for recomposing disrupted territories. The paper proposes a reflection on the topics related to conflict territories and the roles currently played by Cultural Heritage. The recomposition of conflict territories is based on a continuous intercultural approach with important contributions from human rights, genders equality, intercultural dialogue perspectives and the fact of taking heritage as a territorial stabilization factor. The paper presents specific practical cases in the Eastern Mediterranean region where actions on Heritage religious elements collide with the national sovereign of the respective current countries. A comparative study among these different actions proves that the initial clashes can be progressively transformed into strategies able to become the future guideline for the resolution of heritage regional conflicts. These conflicts reflect two discourses: political (with strong links between national identity and religion) and scientific (with a clash between static concept and dynamic vision) where objects interact with the visitors.

ABSTRACT
Many studies have been conducted over the last 20 years to determine and measure factors that affect the walkability of city streets. Walkability is an essential factor in deciding whether a city is green or sustainable. This paper creates a comprehensive walkability index by analysing built environmental indicators that affect walkability. This research was conducted on mixed land use streets in Cairo, Egypt, combining the results from an online survey and a walkability assessment model developed by multi-criteria decision analysis techniques. The results were based on a three-pillar approach starting with the theoretical background to frame the walkability indicator, numerical assessment over the Egyptian cases using a multi-criteria decision-making (MCDM) technique and a qualitative user perception survey. Our results confirm that determining to what extent Cairo’s streets are walkable is crucial to enhancing pedestrians’ perceptions of the walking environment. Furthermore, the results illustrated the essential factors within the built environment indicators that influence pedestrian walking behaviour.

ABSTRACT
Since the 1960s, new town developments within large metropolises have been widely adopted to decongest the city centres, especially in Asian cities. This paper provides a brief account of the liveability dimensions of two new townships developed in large metropolitan areas: Senri New Town in Osaka and Purbachal New Town in Dhaka. The study primarily draws on master plans of the two developments to identify how the components of the plans reflect the physical, social, functional and safety dimensions of a proposed liveability framework. The methodology combines a review of masters plans with scholarly and grey literature on the two new town developments. The findings show while the social and functional dimensions are integrated with Senri New Town; Purbachal New Town, though more recent, appears to have missed opportunities for diversifying density, social mix and mass transit. The paper concludes that the comparative case, Senri-New Town provides insights on how public-private people participation can leverage citizen-centred design for more liveable residential living environments in developing cities.

ABSTRACT
Nowadays, uncontrolled urbanisation is one of the major problems facing Algerian oasis regions. The monitoring and evaluation of its landscape transformations remain a key step for any oasis sustainability project. This study highlights the evolution of spatial growth in the city of Adrar in southern Algeria during the period 1986-2016 by establishing a Spatio-temporal mapping and landscape quantification. The methodological approach is based on a multi-temporal analysis of Landsat satellite images for 1986, 1996, 2006 and 2016, and the application of landscape metrics. The results show two opposite spatial trends: significant growth of built-up areas against an excessive loss of palm groves. The landscape metrics allowed the identification of a progressive fragmentation process characterising the palm groves. Thus, the findings of this study show the utility of satellite imagery and landscape metrics approach for monitoring urbanisation patterns and assessing their impacts on oasis ecosystems.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Participation in decision-making processes foreshadows enabling citizens, communities, non-governmental organizations and other interested parties to influence the formulation of policies and laws affecting them. The purpose of this study is not only to review Lithuanian legal documents but also to analyse recent processes in Kaunas city planning. Kaunas city is undergoing various urban processes, which do not always meet the needs of the community. This study presents an analysis of the forms of community involvement in the urban planning processes and survey data on the effectiveness of community involvement. The methodology requires using a sociological survey with representatives of the city community and a comparative analysis between legal obligations and actual urbanization process.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The phenomenon of planning involving citizen’s participation in planning literature has been from the second half of the 20th century. Indeed, different methods and techniques have been used in the process. However, participatory practices are time-consuming and negotiations are tiresome. Accordingly, the integration of developing digital technologies into participatory processes has been seen as a potential to reach large audiences and provide time-space independence. Within the scope of this research, a detailed literature review was done regarding e-participation, and ten (10) examples representing the upper levels at the ladder of participation were examined within the context of the project, participation, and socio-technical criteria. SWOT analyzes were structured by grouping similar applications, and current trends for the use of e-participation in urban design have been revealed. The analysis showed that citizens e participation- participation tend to allow citizen design or location-based interaction, playful interfaces and game elements which can be sources for encouragement.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
For decades, numerous countries have been witnessing the Street Children phenomenon where millions of children worldwide are subjected to risks. Despite the crucial role of intermediate non-residential interventions - using drop-in centers- in protecting and rehabilitating street children, there is a paucity of research addressing the quality of design of these centers and how architecture might influence their operational process. Those observations invite investigating drop-in centers used in practice from a design perspective and question adapting architectural applications for humanitarian emergencies, focusing on “Child-Friendly Spaces”. The study aims to provide solutions for better quality design, facilitating operational challenges. The methodology undertakes the investigation through primary and secondary axes. This involves conducting literature and international precedents review and secondarily, an Egyptian contextual first-hand documentation and qualitative analysis of selected centers.

ABSTRACT
The notion of “Cultural heritage” is quite modern compared to other humanistic fields developed in the last century. Conservation as a science has emerged and took shape during international conventions and treaties in many places in Europe and developed various frameworks to recognize the heritage and its value but based on “Eurocentric bias” criteria. The fact of sharing universal values and common practices during the age of globalization had a significant impact on conservation actions in contexts utterly different from western societies and don’t share the same historical or cultural dimensions. Therefore, this study traces the history of the evolution of conservation in the west from two perspectives; the historical one and the developing methodologies, and the philosophies behind the main theories in conservation. Cultural heritage is a reflection of the identity of the society and its past; thus, this study outlines the development of conservation practices in Egypt within the international approaches in a chronological order to investigate the social response and the impact of the political and cultural influence of the cultural consciousness of the society and the conservation actions in the Egyptian context. Furthermore, to investigate the contribution of international charters in developing national policies in Egypt.

ABSTRACT
The present study argues that the urban form of affordable housing projects affects safety and security. The study examines the level of safety and security in the Prince Fawaz project proposing recommendations that enhance it. Theories and approaches concerned with the environmental crime are initially reviewed. Then, urban and architectural features as well as crime rates and patterns are documented. Also, trace and behaviour observations are carried out. The observations monitored urban features and behaviours associated with crime or fear of crime. Residents’ perception for security and fear of crime is extracted through a questionnaire. A Space Syntax is processed and linked with the questionnaire and observation outputs. Observations demonstrate a semblance of fear of crime which is supported by records of car and home theft. Although the questionnaire reflects a suitable level of security, it points to peripheral spaces and areas around mosques and shops as the less secure. However, enhancing security in the Prince Fawaz project requires urban interventions including controlling access to peripheral spaces, reviving areas detected to be unsafe, repositioning elements causing visual obstacles and enhancing appearance by vegetation and sustainable maintenance. Besides, reformulating the movement network so that an appropriate integration between residents and strangers is achieved. On the conceptual level, the study proves that none of the theories of environmental crime can act as a comprehensive approach; but each can partly work.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The interaction between transport, land-uses and travel patterns produce diverse transportation problems in urban cities with traffic congestion as the most visible manifestation. Traffic congestion is a frequent phenomenon in most cities around the globe. This paper reviews the interaction between land-use traffic congestion through published literature. The objective of this study is to encourage and provide researchers with future research directions in land-use and traffic congestion. For this purpose, a systematic review was performed analysing 45 articles from the year 2010 to 2020 using a descriptive approach. Subsequently, the results of the study show that although the interaction between land-use and traffic congestion has gained currency in developed countries far less is known on this subject in developing parts of the world, though new evidence is steadily accumulating. Consequently, limitations of this work are presented, opportunities are identified for future lines of research. Finally, the conclusion confirms the need for further research addressing the methodological concerns.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
“SIMURG_CITIES” is the research and development project that is developed under the main project named SIMURG: “A performance-based and Sustainability-oriented Integration Model Using Relational database architecture to increase Global competitiveness of Turkish construction industry in industry 5.0 era”, is a relational database model that is currently being developed in a dissertation for performance-based development and assessment of sustainable and sophisticated solutions for the built environment. This study aims to analyze the key performance indicators (KPIs) at «Cities Level» for the smart city concept that is referred to as «Layers» in the master project. KPIs for the concept of a smart city are determined by using the meta-analysis technique. Hence, the three most reputable urban journals issued from 2017 through 2020 are reviewed in this study. In addition to this, models of smart city frameworks/assessment tools/KPIs are reviewed within the context of this paper; environment, economy, and governance were found to have domain themes on urban sustainability according to the literature review. Consequently, efficient and integrated urban management, environmental monitoring and management, public and social services of urban development, and sustainability are found to be the most important dimensions in urban and regional planning. SIMURG_CITIES evaluation models for urban projects can use the findings of this paper.

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

Compositions of iron-meteorite parent bodies constrainthe structure of the pr...Sérgio Sacani
Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.
SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

Anti-Universe And Emergent Gravity and the Dark UniverseSérgio Sacani
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

different material parts are being joined
together to provide a better combination of
properties (Wegst et al. 2015). However, the
rapid growth in technological development of
the 21st century played a great role in the
emergence of advanced composite materials
and its construction methods. It has also
presented its self to be more dynamic, and as
well made contemporary buildings to be more
attractive and unimaginable, therefore based
on some of the outstanding attributes advance
composite material portray, the use and
application of traditional building material and
its construction method tends to decline with
time in the nearest future (Karbhari, 1998).
Advanced composite material has therefore
presented its self with a much greater value
and sustainability; the impact of these materials
has also made contemporary buildings and
their various design type embrace a much
more dynamic and flexible system of
construction.
Building Materials can be described as the
embodiment of a building or a structure, and it
production accounts for 30-50% consumption
of raw materials worldwide (Tagnit-hamou and
Soliman, 2018). The early discovery of building
materials cannot be undermining rather it can
be registered as one which has gone through a
unique and extraordinary historic path of
discovery, starting from the early civilization of
the cave men who had to source material like
wood, stones strands to create shelter that can
stand as a form of protection from the
harshness of the weather and harmful element
of the environment of stay.
Ever since then man have never remained
seldom in the search for possible innovative
means to create materials that can go in hand
with it environment, though the 19th century
remains a remarkable era that can be
remembered for it industrialization
and the expansion of modern construction tec
hnological development which majorly had a
great influence on building materials and its
method of construction (Zabihi, 2010). Though
the acceleration in advancement in
technology of the past and much more
innovative ideas today has lead in the creation
of building materials that are gradually coming
to the lam light. Today advance composite
material can be regarded as one of the
product of effective technological
development of the 21st century (Ljungberg,
2007). These innovative building materials tend
to play a great role in contemporary buildings,
in terms of environmental friendliness and
sustainability and as well tend to bridge the
gap between already existing traditional
building materials.
1. Materials and Methods
This research employed the case study method
for identifying various buildings across the world
that have employed the instrumentality of
environment friendly materials for construction
and composition. The sources of the identified
buildings are the internet and other archival
materials which considers the use of
sustainable construction materials for the
purpose of their composition. A checklist was
also prepared for the purpose of obtaining up-
to-date information about the selected
buildings and also prepare a basic appraisal
and evaluation criterial for the purpose of
determining the extent of sustainability of the
identified buildings.
2. Discussions
The awakening of 21st century paved way to
vast technological advancement. However,
these technological advancements majorly cut
across the construction industry, by influencing
its building material types as well as its methods
of construction. This advancement further
brought about a dynamic change in the
building industry, by therefore producing
innovative building materials (advance
composite material) that offer unique
properties as well as wide variety of functions,
and structural performance qualities that are
sustainable and environmentally friendly, and
are as well very much impossible to archive
with normal traditional building materials
(Akadiri et al., 2012)
in terms of it:
New aesthetic possibilities and ability to
mould complex fluid and create design
of different forms, shapes and styles
Being able to Provide special
integrated surface finishes and effects
Being able to provide significant savings
in weight usually up to 15%
Being able to ensure superior durability
with degradation through life
Being able to provide Rapid installation
and cost on site
Being able to Unlock the possibilities of
architectural design
To ensure Temperature and chemical
resistance
To ensure Flex performance
To ensure Dimensional stability.
With the above mentioned qualities, architect,
designers and engineers tend to play a vital
role with the use and application of

contemporary building material. They are
therefore exposed with the challenges of new
idea, as well as new knowledge and
understanding of the nature of these new
material, such as their physical and chemical
properties, their structural properties, their
characteristics in fire, their interaction with
other material as well as their anticipated
durability for any given situation, cost,
maintenance requirement and potential for
recycling and other environmental issues such
as embodied energy. However, it also further
relates to it impact in terms of health and
safety, as well as its multiplicity towards
aesthetic properties.
Advance composite materials as a
contemporary material are mixture of two or
more materials to form a composite material. It
is classified as an advance composite,
because they are determined by unusually
high strength fibers with high stiffness or
modulus of elasticity characteristic compare to
other materials or composite, such as fiberglass
and concrete. Advanced composite systems
are divided into two basic types, thermosets
and thermoplastics. Thermosets are by far the
predominant type of composite in use today
while Thermosets are subdivided into several
resin systems including epoxies, phenolic,
polyurethanes, and polyimides. These, epoxy
systems currently dominate the advanced
composite industry today.
The first inception of advanced composite
materials can be traced back to the past 50
years with a wide range of demanding
applications. However, one of its very first
commercial application was noted shortly after
the Second World War, with a USA Company
named Mine Hunters, which introduced
advanced composites into military vehicles, as
well as opened doors to the multiplicity of a
much more advanced composite material that
are now applicable in different forms and
functions in today’s modern world. Advanced
composite materials are now the common
material for high performance super yachts,
large wind turbine blades, modern aircraft, and
sports and leisure equipment including ski’s,
snowboards and surfboards. However, they are
also being widely used in construction,
because they tend to offer significant weight
savings and their ability to form complex
shape, give architects greater freedom in
design. Nguyen, Mendis, Ngo, Tran, & Nguyen,
(2013), noted that the applications of advance
composite material has witnessed and
reflected a great shift in the construction
industry through series of research and project
carried out since the 1990s. However, its market
share distribution has risen more than 25%,
therefore projecting the construction industry
as the second largest field in the application of
advance composite, See Fig.1.
Fig.1: Shows a chart showing the differential scale in the
application advance composite material (Nguyen, Mendis,
Ngo, Tran, & Nguyen, 2013).
An example of such is exhibited in Heydar
Aliyev Center designed by Zaha Hadid
Architects. The building which is a
contemporary building characterized with a
complex geometry,it also represent a wide
contrast from traditional building materials,
because some of it major construction material
used were advance composite material in
form of Glass Fibre Reinforced Concrete
(GFRC) and Glass Fibre Reinforced Polyester
(GFRP), they were chosen as ideal cladding
materials, because they allow for powerful
plasticity in building design while responding to
very different functional demands related to a
variety of situations, see Fig 2

Designing with advance composite materials
opens up a wide range of design possibilities, it
can also optimize the performance of a
structure by the modification of the building
blocks of the materials. The chemistry of the

resins can as well be modified to produce
materials with specific characteristics for
specified use.
3.1 Characteristics of advance composite
material
Nguyen, Mendis, Ngo, Tran, & Nguyen, 2013,
described Advance Composite materials, to
possess high advantages in strength, stiffness,
low density, as well as manufacturing flexibility;
therefore, their potential in replacing traditional
building materials (such as concrete, aluminum
and steel) in building construction has become
attractive. Advance composite materials are
not only limited to building material alone,
rather their use and application also have a
broad and proven application in design
flexibility as well as dramatic shapes, styles and
forms in architectural aesthetics, interior finishes
and landscaping design etc. one of The
biggest characteristics of modern day
advance composite materials are the fact that
they are light in nature but also very strong to
stand the taste of time. They are also
innovatively driven by the choice or
specification of an appropriate combination of
matrix and reinforcement materials. It can
therefore be made to exactly meet the
specified requirements of any particular
application. However, based on its outstanding
attribute, advance composite materials tend
to plays a vital role in taking construction,
design, aesthetic and remodeling forward in
this contemporary era. Therefore, with recent
technological advancement, advance
composite materials are now designed to
respond with various stimuli which are changed
significantly into predictable manner in
response to the environment.
3.2 Aesthetics possibilities with advance
composite material
Aesthetic problem due to complexity in design
and architectonics has been notable in the
construction industry, as a result of the low level
of technology involved in traditional building
material and its method of construction.
Architects, designers and engineers show great
interest in the use of advance composite
materials in the formation and composition of
contemporary buildings, to advance
composite material for the ability to allow cost
effective realization of unique shapes, styles
and forms as well as flexible aesthetics, while
accommodating architectural designs and
needs. The long-term durability, weathering
resistance, and the exceptional mechanical
properties have recently suggested the
adoption of advance composite material for
building façade systems in an increasing
number of buildings worldwide (Berardi &
Dembsey, 2015).
However contemporary buildings and
structures built from advance composite
materials has revealed and proven its flexibility
by allowing all forms, shape and style of
aesthetics to be achievable with high durability
and tensile strength. Nonetheless Designs with
advance composite materials are easily
archived in time and safety. Advance
composite materials are innovative candidates
to be used in contemporary building façade
and aesthetic systems because they offer
excellent performance and cost effectiveness
in aesthetic and complex designs.
With the benefits of high strength and stiffness,
low density, and highly flexible shaping,
advance composite material become
potential candidates in the replace of
traditional building materials (such as aluminum
and steel) in civil applications. For example,
advance composite materials contribute up to
50–70% weight reduction as an alternative to
traditional metal-based materials. In addition,
the manufacturing flexibility of advance
composite material products is well-suited with
the demands of architects and engineers in
designing complex building structures such as
the façade systems while maintaining
mechanical properties and durability.
Therefore, it can be noted that one of the
major roles advanced composite material play
in contemporary buildings are the possibility of
new aesthetic. However this can be
considerably high due to the vast use of
advance composite materials in the twenty-first
century buildings and structures. Since the
introduction of advance composite material in
buildings, it has paved way for some many
fabricators to produce composite materials
from recycled and renewable materials in
other to create building elements for buildings
facades and the general aesthetics of
buildings and its environment.
Composite materials, such as Glass fiber
reinforced polymers (GFRPs), carbon fiber
reinforce polymers (CFRPs), possess the
advantages of high strength, stiffness, low
density, and flexibility; therefore, their potential
in replacing traditional materials (such as
concrete, aluminum and wood) in building
aesthetics and facade has become an
interesting and attractive one in the building
industry today. See below Fig.3, Fig.4 and Fig.5

3.3 The influence of advanced composite
material in existing buildings and structures
Advance Composites materials are one of the
most widely used materials today, because of
their innovative and sustainable adaptability to
different environmental and structural
condition. It also allows for the combination
with other materials, so as to serve specific
purposes and exhibit desirable properties in
existing buildings and structure. Therefore, it
uses and application in buildings and structures
they are selected carefully based on it
intended required purpose for the repair of
damaged elements in buildings or structural
elements, so as to help prevent futuristic
occurrence of failure of any kind in the long run
use of the building or structure. However, the
use and application of advance composite
materials in existing buildings are to enable
performance quality, structural stability and a
functional structure that can stand the taste of
time.
Advanced composite material like fibre
reinforced polymer are proven technology
used for upgrading and strengthening of
concrete, masonry, timber as well as steel
structure. Generally advance composite
materials have exceptionally high strength, yet
they remain very light and easy to work with. it
application has cut across all areas of
construction ranging from increase in capacity
of existing buildings, bridges, seismically
upgrading structure, correcting design or
construction error and allowing for further
modification or change in use. Fig.6 & 7 shows
below some of the application of fibre
reinforced polymer and some of it advantages
Fig. 6: shows repair of concrete beams with ACM.

Some of the advantages of fibre reinforced
composite are:
Economy and durability
Ease of application
Extremely high tensile strength
Outstanding fatigue behavior
Absolute resistance to corrosion
Ability to upgrade structure while in
use
upgrade possibilities even with
limited access
A rhetorical studies conducted by (T. Keller,
2001) has proven that Fibre-reinforced
polymers (FRP) have found increased
application in bridge and building construction
in recent years. This is predominantly due to the
advantageous properties of these materials,
such as low self-weight, high strength, free
formability and substantial resistance to
corrosion and fatigue. Chiewanichakorn &
Toranzo, 2011, also pointed out that a
comprehensive study on Seismic retrofitting of
st. Joseph Hospital revealed the use and
application of advanced composite
materials for the enhancement of
column, slab, wall and beam elements. It also
further depict the practical use and
application of advance composite material in
archiving certain structural standards as
assigned by the united states government, see
below fig.8, fig.9.
Fig.7: depict the use of advance composite in the healing
of concrete spall on wall (Chiewanichakorn & Toranzo,
2011).
The application of advance composite
material enabled protection against concrete
spalling and as well as reduced the possibility
of body injury. Basically the use of advanced
composite material can contain any form of
damage to the concrete that could occur
during a seismic event.

of concrete spall on wall (Chiewanichakorn & Toranzo,
2011).
Columns are retrofitted with advance
composite material. Advance composite
wraps are applied in circular direction to
supplement the transverse steel reinforcement
and to as well increase the shear capacity of
the columns and to provide plastic hinge
confinement.
3.4 Advanced composite material as an
innovative and sustainable building material for
the feature
Advance composite materials are currently
revolutionizing architecture and design. Their
applications in the field of construction have
allowed the progressive replacement of
traditional materials and many barriers that
designers used to find when implementing
projects with a futuristic design have
disappeared. Up until now, advance
composite materials have been more
commonly used in repairs, secondary structures
and huge self-supporting structures, such as
domes. However, it’s innovative drive open
door for architects and engineers to develop
more complex works which will satisfy the
creativity of some designers and architects. It
also offers the desire to challenge the
established certain canons when designing
buildings and unique works, These which are
only possible with composite materials, since
we take advantage of the combination of the
low weight of these materials and their ability
to be molded in such complex shapes
(Isabel&Soler, 2016).

3. Conclusion
The emergence of composite materials in the
building industry came as a result of certain
limitation and factors over traditional building
material. However based on the versatility of
advance composite materials, a wide range of
construction development has been achieved
ever since its inception in to the building
industry. The use and application of Advance
composite material enables broad and proven
application in contemporary building, it
flexibility in design also enables great
achievement in complex geometric shapes,
styles, and forms as well as a much more
flexible method of construction
Design complexity can been resolved with the
ability of advance composites materials.
However it further plays a very unique role in
the repairing of existing buildings and structure
due to its unique characteristics over traditional
building materials with high flexibility
characteristics. There is a great possibility of
achieving new aesthetics in construction and in
repair of old buildings.
Advance composite materials tend to offers a
very wide range of applications, properties and
advantages in present day building
technology which are far impossible with
traditional building materials such as new
aesthetic possibilities, abilities to mould
complex fluid and creative form which
integrate special surface finishes and effect,
significant saving in weight usually up to 15%,
superior durability with degradation through life
cost on site and less degradation, flex
performance, dimensional stability, rapid
installation as well as unlocking the possibilities
of architectural design. Therefore,
composite material can be assessed as a new
intervention in the modern day building industry
with so many credits against traditional building
material.
