1. The document discusses the use of nanosilica to improve the properties of cement composites containing industrial waste like fly ash. Test results show that optimal additions of nanosilica increase the short-term and long-term strength as well as density of both ordinary Portland cement and fly ash cement composites.
2. Microstructure images indicate that nanosilica fills the pores in the cement matrix, resulting in stronger and denser composites. While nanosilica improves short-term properties, these benefits were not confirmed in the long-run when used alone. However, when fly ash waste is added to cements along with nanosilica, the enhanced properties are retained both in the short

The main objective of this work is to study the mechanical strength and durability of the concrete when the particular cement dosage in concrete in replaced with Nano silica powder. However it is expected that the use of Nano-silica in concrete improve the strength properties of concrete. Also it is an attempt made to develop the concrete using Nano sized particles as a partial replacement of cement, which satisfies the various structural properties of concrete like compressive strength and tensile strength. It is expected that the final outcome of the project will have an overall beneficial effect on the utility of Nano-silica concrete in the field of civil engineering construction work.

EFFECT OF NANO-SILICA ON CONCRETE CONTAINING METAKAOLINIAEME Publication
In this paper the results of an experimental investigation on the use of Metakaolin (MK) and Nano-Silica (NS) on various properties of concrete are presented. Metakaolin and Nano-Silica are used as partial replacement of cement for the preparation of concrete. In the present investigation initially cement is partially replaced by Metakaolin 5% and 10% by weight. Further investigation is carried out by combined replacement of Metakaolin at 5% and 10% with Nano-Silica at 1%, 2% and 3% by weight of cement. For structural applications the various properties, such as compressive strength, split tensile strength, modulus of elasticity and flexural strength of M25 grade concrete containing MK and NS are evaluated and the results are compared with the controlled concrete. Based on the test results, it can be observed that concrete prepared with a combination of 5% MK and 2% NS indicated increased strength compared to the controlled concrete.

Effect of Nano Silica on the Compressive Strength of Concreteijtsrd
Concrete is one of the most important materials in the construction world. In the present scenario, due to the various industrialization, especially in the urban areas, the demand of construction work increases progressively. Due to which there is very high demand of concrete. So, it is very important to improve the durability and properties of concrete. For this there are various admixtures which are partially replaced with the cement like fly ash, slag, silica fumes, rice husk etc. However, in the present situation, Nano technology comes as a very faithful approach for improving the strength and durability of the concrete. In this project, M30 concrete is used and we use Nano silica of size 236nm as a partial replacement in concrete. Nano silica enters into the pores of the concrete and sets early due to which the permeability and strength of concrete are improved. An experimental analysis has been done by replacing the cement with Nano silica by increasing its percentage as 0.5 , 1 , 2 and 3 b.w.c. The results show that with increase in amount of Nano silica, the compressive strength increases up to 3 , however, if amount of Nano silica goes beyond 3 , the compressive strength of concrete starts decreasing. In these experimental tests, there are 10 cubes prepared with the sample and tested at 7 and 28 days.

Effect of Nanosilica and Sugarcane Bagasse Ash on Strength of Concrete- A Reviewpaperpublications3
Abstract: Nowadays the use of cement in construction work is extremely increased. Also new big problem arrived i.e. the shortage of natural resources like stones, aggregate, sand, water, etc. Huge production of cement produces foul gases causes’ air pollution and increases temperature of earth. Generally the one tone production of OPC releases approximately one ton of carbon dioxide (CO2) to the atmosphere. Sugar cane bagasse ash (SCBA) is one of the wastes produced from the sugar industry causes serious environmental problem. From past research it is found that, for conservation of natural resources and utilization of waste product the Nano- silica (NS) and Sugar cane bagasse ash (SCBA) as a supplementary material for cement to improve their strength and performance. Nano Silica has been partially replaced in ratio 2%, 4% and 6% by weight of cement in concrete [13]. Bagassse Ash has been partially replaced in the ratio 0%, 5%, 15% and 25% by weight of cement in concrete [20]. This paper includes review on the strength of concrete by using Nano Silica and Sugar Cane Baggase Ash and its different properties.

The use of cement reasons air pollution so we can regulate it by replacing some amount of cement with marble dust.
In Pakistan budget is the key problem. Marble powder and kaolin clay are inexpensive. Marble powder is a waste.
Marble stone industry generates both solid waste and stone slurry. Leaving this waste material to the environment directly can cause environmental problem.

India's Water Equation:Some Data Concerns & its Interpretations Mainak Ghosal
Water is the most precious of all natural resources for human existence. But management of water resources and river basins must ensure functioning of the ecosystem as a paramount goal. Extreme conditions of resource availability - both paucity and excess are detrimental to human life and property. In view of the severe flood occurrences of recent years, developed economies have passed Flood Management Directives with the objective to minimise and manage flood-related risks to humans, the environment and property. The seminar aims to address these issues.
OBJECTIVE OF THE SEMINAR
To bring together all stakeholders to consider a holistic approach, discuss the challenges and opportunities and make recommendations to the Government.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
