The document summarizes the evaluation of different types of green concrete being investigated by the Danish Centre for Green Concrete. The center aims to reduce the environmental impact of concrete by developing new technologies. Four ways to produce green concrete are described, including using conventional and industrial residual products and cement with reduced environmental impact. Preliminary results show the green concrete types can achieve similar mechanical properties and durability as conventional concrete. A life cycle screening of a bridge found that three green concrete column designs reduced CO2 emissions by 30% or more compared to a reference design, fulfilling the center's environmental goals.

Using fly ash as replacement of cement & aggregate
This document presents a thesis study on utilizing fly ash as a partial replacement for cement and fine aggregates in concrete. The study was conducted by Mohamad Rkein under the supervision of Professor Sabaratnam Prathapan and Associate Professor Krishnan Kannoorpatti. The study aims to determine the feasibility and effects on mechanical properties of using fly ash to replace cement and fine aggregates in concrete mixtures. Tests were conducted on workability and compressive strength of concrete with varying replacement levels of fly ash at 7, 28, and 56 days. The results indicate that fly ash can effectively be used as a partial replacement material in concrete and may provide benefits to strength properties and reduce environmental impacts.

Concrete is the most widely used man-made construction material in the world and is consumed second only to water on this planet. It is obtained by mixing the cementitious materials, water and aggregates in the required proportions. However, the various required performance attributes of concrete including strength, workability, dimensional stability and durability, often impose contradictory requirements on the mix parameters to be adopted, there by rendering the concrete mix design a very difficult task.
The increase in global warming has resulted a wide range of change in earth’s temperature, the source being emission of carbon dioxide gas from the production process of cement. Use of naturally available pozzolanic waste materials (fly ash & granite powder) as a partial substitute of OPC cement in mortar mix has seen a wide potential in the utilization of these waste material and also enhancing the properties of mortar mix and thus reducing the environment impact caused by manufacturing of cement. In this study the effect of using fly ash & granite powder is used as a partial substitute of ordinary port-land cement and to reduce the cost of the cement.
An investigation was conducted to determine the suitability of using fly ash (bi-product from thermal power plant) and waste granite powder as partial replacement for cement for concrete production. Apart from the control concrete sample which had 100% cement all the other samples were treated to 20%, 40%, 60%, 80% and 100% replacement of cement with flyash and granite powder. Concrete cubes of 150mmx150mmx150mm, cylinders of 150mm diameter and 300mm height, beams of 100mmx100mmx500mm were made with the various proportions of cement, sand and coarse aggregates in a mix ratio of 1:2.2:3, water -cement ratio of 0.50 and cured over 28 days. The results of compressive strength tests show that the strength of the concrete cubes with varying amounts of cement and fly ash and granite powder changed marginally. This was interpreted to mean that the partial replacement of cement with fly ash and granite powder up to 20% in concrete results in about 1.4% increase in the strength of the concrete. The compressive strength of concrete cubes is 33N/mm2, flexural strength of concrete beams is 5.10 N/mm2 and split tensile strength of concrete cylinder is 2.34 N/mm2 for 20% replacement.
Partial Replacement of Cement by Fly ash in Concrete Mix Design
This document discusses the partial replacement of cement with fly ash in concrete mix design. It begins with an abstract stating that concrete is an important construction material and that adding other materials can change its properties. The document then discusses how fly ash is a byproduct of coal combustion that can be used to partially substitute cement. When used in concrete, fly ash improves strength properties while requiring less energy to produce than ordinary Portland cement. The document provides details on fly ash classification, properties, advantages of using fly ash in concrete, and provides an example mix design showing the reduced quantities of cement, water and fine aggregate needed when partially substituting cement with fly ash.
INVESTIGATION ON FLY ASH AS A PARTIAL CEMENT REPLACEMENT IN CONCRETE
The use of Portland cement in concrete construction is under critical review due to high
amount of carbon dioxide gas released to the atmosphere during the production of cement. In
recent years, attempts to increase the utilization of fly ash to partially replace the use of Portland
cement in concrete are gathering momentum. Most of this by-product material is currently
dumped in landfills, creating a threat to the environment.
Fly ash based concrete is a ‘new’ material that does not need the presence of Portland
cement as a binder. Instead, the source of materials such as fly ash, that are rich in Silicon (Si)
and Aluminium (Al), are activated by alkaline liquids to produce the binder.
This project reports the details of development of the process of making fly ash-based
concrete. Due to the lack of knowledge and know-how of making of fly ash based concrete in the
published literature, this study adopted a rigorous trial and error process to develop the
technology of making, and to identify the salient parameters affecting the properties of fresh and
hardened concrete. As far as possible, the technology that is currently in use to manufacture and
testing of ordinary Portland cement concrete were used.
Fly ash was chosen as the basic material to be activated by the geopolimerization process
to be the concrete binder, to totally replace the use of Portland cement. The binder is the only
difference to the ordinary Portland cement concrete. To activate the Silicon and Aluminium
content in fly ash, a combination of sodium hydroxide solution and sodium silicate solution was
used.
Manufacturing process comprising material preparation, mixing, placing, compaction and
curing is reported in the thesis. Napthalene-based superplasticiser was found to be useful to
improve the workability of fresh fly ash-based concrete, as well as the addition of extra water.
The main parameters affecting the compressive strength of hardened fly ash-based concrete are
the curing temperature and curing time, The molar H2O-to-Na2O ratio, and mixing time.
Fresh fly ash-based concrete has been able to remain workable up to at least 120 minutes
without any sign of setting and without any degradation in the compressive strength. Providing a
rest period for fresh concrete after casting before the start of curing up to five days increased the
compressive strength of hardened concrete.
The elastic properties of hardened fly ash-based concrete, i,e. the modulus of elasticity,
the Poisson’s ratio, and the indirect tensile strength, are similar to those of ordinary Portland
cement concrete. The stress-strain relations of fly ash-based concrete fit well with the expression
developed for ordinary Portland cement concrete.

IRJET- Partial Replacement of Sand with Sawdust in Concrete
This document presents research on partially replacing sand with sawdust in concrete mixtures. Sawdust was used to replace sand at 5%, 10%, 15%, 20%, and 25% by weight. Concrete cubes, beams, and cylinders were cast and tested for compressive, flexural, and split tensile strength at 7, 14, and 28 days. The results showed that compressive, flexural, and split tensile strength generally decreased as the sawdust replacement ratio increased. However, satisfactory strength results were obtained at a 5% sawdust replacement ratio for compressive and split tensile strength tests, and at a 10% replacement ratio for flexural strength tests. Using sawdust in concrete provides benefits like lighter weight

This document studies the strength characteristics of concrete when sand is partially replaced by granulated blast furnace slag (GBFS). Tests were conducted by replacing sand at 10%, 20%, and 30% with GBFS at various water-cement ratios of 0.4, 0.5, 0.6, and 0.7. The compressive strength was tested at curing ages of 3, 7, 14, 28, 56, and 90 days. The results show that replacing sand with 10-20% GBFS increased the compressive strength at lower water-cement ratios of 0.4-0.5. However, replacing sand with 30% GBFS decreased the compressive strength.

PARTIAL REPLACEMENT OF AGGREGATES BY BURNT BRICK BATS AND LATERITIC FINES IN ...International Research Journal of Modernization in Engineering Technology and Science
As concrete is the most abundant material used in the world, it contains aggregate content of around 60 to 70 %. Since aggregate are being used rapidly there has been a scarcity in the avaibility of these materials. This research investigates the effect of partially replacing aggregates by burnt brick bats and lateritic fines in concrete respectively for M25 grade concrete. The incorporation is done for 5%, 10% and 15% of burnt brick bats for coarse aggregate and by talking 15% of lateritic fines as constant for fine aggregate by conducting compressive strength test which gave the optimum value of 15% for natural sand. The compressive strength, split tensile strength and flexural strength was conducted. The results showed density of of the concrete incorporating brick and laterite was lower compared to conventional concrete, the concrete with 5% burnt brick and 15% lateritic soil showed increased strength for 7 days compared to normal concrete but when 28 days test was conducted the strength was similar to conventional concrete. The split tensile and flexural strength of replaced concrete was found to be lower than the nominal concrete.Cover letter

Cement is a major construction material worldwide. However, given the escalating costs of cement and the environmental hazards associated with the use of cement there is need to develop alternative, costeffective, non-conventional, locally available materials, especially those that can partially or wholly replace cement. This paper presents the results on the study of the effect of local brewery waste and bitter cassava flour on the compressive strength and shrinkage of plaster. The test was made with cement replaced by local brewery waste or bitter cassava (10-50%) and cement/sand mix as a control. The results showed an optimum of 20% cement replacement with bitter cassava for plaster mortar for high cost houses (18.1Mpa) and 10% cement replacement with local brewery waste for plaster mortar for low cost houses (2.1Mpa). Result show a maximum shrinkage of 8mm at 50% replacement with bitter cassava and zero shrinkage for 50% replacement with local brewery waste. Furthermore only the control, 40% and 50% with bitter cassava flour showed cracks of about 2mm for mix ratio 1:3 and 1:4.

Performance of lateritic concrete under environmental harsh condition
This document investigates the performance of lateritic concrete under different environmental conditions by varying the ratio of laterite to fine aggregate in concrete mixes. Cubes made with different ratios (0%, 10%, 20%, 30%, 40%) were subjected to high temperatures, wetting and drying cycles, and chemical exposure. The results showed that compressive strength generally decreased with increased laterite ratio under wetting/drying cycles but increased when exposed to magnesium sulfate. A ratio of 20% laterite attained the highest strength of 12.9 MPa after heating to 100°C, indicating it provides optimal performance under harsh, tropical weathering.

This document reviews research on using bottom ash as a partial replacement for sand in concrete. It summarizes findings from 10 research papers on the effect on properties such as workability, density, compressive strength, and splitting tensile strength. The key findings are:
1) Workability and density of concrete decreases as the amount of bottom ash replacement increases, due to the lower specific gravity of bottom ash compared to sand.
2) Compressive strength is initially lower for bottom ash concrete but can reach or exceed normal concrete strengths at later ages, with replacements of 30-40% bottom ash achieving strengths equivalent to normal concrete at 28 days by 90 days.
3) Splitting tensile strength also decreases with
Partial replacement of wood ash and quarry dust with cement and sand to study
This document summarizes a study that partially replaced cement and sand in concrete with wood ash and quarry dust to examine the strength properties. Wood ash and quarry dust are industrial byproducts that can potentially be used as supplementary cementitious materials. The study developed concrete mixes with varying replacement levels of wood ash for cement and quarry dust for sand. The compressive strength of the concrete mixtures was then tested at different curing periods. The results showed that compressive strength decreased with higher levels of wood ash but increased with longer curing times. An optimal replacement level of 45% sand with quarry dust was also identified. The aim was to utilize industrial waste materials to reduce the cost and environmental impact of concrete production.

This document summarizes a study on the impact of adding a colloidal admixture to self-compacting concrete used in bored piles constructed in mud. Seven mixtures of mud with varying percentages of sand were created and used to fill PVC test piles. Self-compacting concrete with and without a colloidal admixture was then poured into the piles. Tests on cores taken from different pile locations showed that concrete with the colloidal admixture had higher ultrasonic velocities and compressive strengths, indicating a more uniform and dense microstructure. The mixture with the highest percentage of sand (20%) in the mud performed best when the colloidal admixture was added, demonstrating its role in preventing contamination from sand particles.

This study investigated the use of quarry dust as a partial replacement for fine aggregates in concrete. Fine aggregates were replaced with quarry dust at 0%, 10%, 20%, 30%, and 40% by weight. Concrete specimens were tested for compressive strength, water absorption, and density at 28 days. Results showed that compressive strength increased up to 30% replacement, beyond which it decreased. Water absorption increased with higher quarry dust content, indicating a decrease in durability. Density also decreased with more quarry dust, making the concrete lighter. The study found that 30% replacement of fine aggregates with quarry dust provided optimal results.
Green concrete
This document discusses green concrete, which uses less energy and produces less carbon dioxide than traditional concrete. It can incorporate waste materials like fly ash from coal plants. Green concrete has benefits like lower heat production, better durability, and reduced environmental impact from lowering cement use and carbon emissions. It has applications in bridges, buildings, and roads. While it has advantages, green concrete also has limitations like lower tensile strength compared to traditional concrete. Its use has potential to grow in India by utilizing waste materials and reducing environmental effects.
Iaetsd green concrete

This document presents research on partially replacing sand with sawdust in concrete mixtures. Sawdust was used to replace sand at 5%, 10%, 15%, 20%, and 25% by weight. Concrete cubes, beams, and cylinders were cast and tested for compressive, flexural, and split tensile strength at 7, 14, and 28 days. The results showed that compressive, flexural, and split tensile strength generally decreased as the sawdust replacement ratio increased. However, satisfactory strength results were obtained at a 5% sawdust replacement ratio for compressive and split tensile strength tests, and at a 10% replacement ratio for flexural strength tests. Using sawdust in concrete provides benefits like lighter weight

PARTIAL REPLACEMENT OF AGGREGATES BY BURNT BRICK BATS AND LATERITIC FINES IN ...International Research Journal of Modernization in Engineering Technology and Science
As concrete is the most abundant material used in the world, it contains aggregate content of around 60 to 70 %. Since aggregate are being used rapidly there has been a scarcity in the avaibility of these materials. This research investigates the effect of partially replacing aggregates by burnt brick bats and lateritic fines in concrete respectively for M25 grade concrete. The incorporation is done for 5%, 10% and 15% of burnt brick bats for coarse aggregate and by talking 15% of lateritic fines as constant for fine aggregate by conducting compressive strength test which gave the optimum value of 15% for natural sand. The compressive strength, split tensile strength and flexural strength was conducted. The results showed density of of the concrete incorporating brick and laterite was lower compared to conventional concrete, the concrete with 5% burnt brick and 15% lateritic soil showed increased strength for 7 days compared to normal concrete but when 28 days test was conducted the strength was similar to conventional concrete. The split tensile and flexural strength of replaced concrete was found to be lower than the nominal concrete.Cover letter

Green concrete for sustainable construction
Abstract There are many choices in regard to selection of materials in any type of constructions. Due to growing interest in sustainable construction, engineers and architects are motivated to choose the materials which are more sustainable. Green concrete capable for sustainable construction is characterized by application of industrial wastes to reduce consumption of natural resources and energy and pollution of the environment. Replacement of materials over nominal concrete is what makes green concrete more environmental friendly concrete. Marble sludge powder, quarry rocks, crushed concrete and fly ashes are some of the materials used for making green concrete, a sustainable construction. Keywords: Construction Industry, Environmental Impact, Geo-polymer concrete, Green Concrete, Recycled Materials, Sustainable Construction, Virgin Material.
Effects of Carbonation on the Properties of Concrete
Concrete is one of the reliable, durable, economical and acceptable construction materials among the building and construction stakeholders worldwide. Performance of concrete could be threatened especially reinforced concrete by some processes such as corrosion, sulfate attack among others. Corrosion of reinforcement in reinforced concrete can be induced by carbonation process. Even though carbonation initiates corrosion, it has been gathered that carbonation could still be of immense benefits to building and construction industries if its mechanism of operation is understudied. This research work has therefore investigated the effect of carbonation on some selected mechanical properties of concrete such as compressive strength, flexural strength, water absorption and weight changes. Concrete cubes and beams of M15 grade with 0.5 % water-cement ratio were prepared and subjected to accelerated carbonation. Their compressive strength, flexural strength, water absorption and weight changes were determined in accordance with the relevant standards. The outcomes show that carbonation improves all the mechanical properties investigated. The use of carbonation can be positively explored in reinforced concrete provided there is adequate nominal cover.

The document summarizes tests conducted on wall specimens representing a reinforced brick wall construction and a brick-tile cavity wall construction. For each construction, specimens were subjected to compressive, transverse, concentrated, impact, and racking loads to determine their structural properties. Load-deformation data and set measurements were recorded to evaluate how the walls resisted and recovered from different loads. The reinforced brick wall showed behavior under compressive, transverse, concentrated and impact loads. The brick-tile cavity wall was further tested under racking loads in addition to these other loads applied to both wall faces. The results are intended to provide technical data on the performance of these low-cost housing wall constructions.
Silicafume users-manual
Silica fume is a byproduct of producing silicon metal or alloys in electric arc furnaces. It is collected in large baghouse filters after production. Silica fume is a highly reactive pozzolanic material that is used in small amounts to enhance concrete properties. Its primary chemical properties include being highly amorphous and consisting primarily of silica. In concrete, silica fume reacts with calcium hydroxide to form additional calcium silicate hydrates, densifying the microstructure and improving strength and durability.
Ns28 1masnry design
This document provides notation, materials, and design methods for masonry structures. It discusses reinforced and unreinforced masonry design based on allowable stress and strength/LRFD approaches. Key points include:
- Notation used in masonry design is defined, along with materials like masonry units, mortar, and grout.
- Reinforced masonry design uses steel reinforcement to resist tension while masonry resists compression based on equilibrium. Design is checked against allowable stresses.
- Columns must be reinforced and have ties. Allowable axial loads depend on factors like slenderness ratio and reinforcement.
- Examples demonstrate checking unreinforced wall capacity against loads and determining required

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise stimulates the production of endorphins in the brain which elevate mood and reduce stress levels.
Masonry structures confined with concrete beams an dcolumns
This document discusses masonry structures confined with concrete beams and columns. It summarizes that while many unreinforced masonry buildings collapsed in past earthquakes in China, several multistory confined masonry buildings were only slightly damaged. Confined masonry structures place reinforced concrete ring beams at each floor and tie columns at wall intersections to improve seismic performance. Model experiments and practice show that confined masonry can be used for multistory buildings up to 10 stories in seismic zones due to its strength, deformability and reliability.
Masonry beam deflection criteria5.doc
This document examines deflection criteria for masonry beams and lintels. It discusses previous research that showed masonry walls and beams act compositely, with the masonry in compression and beam in tension. Deflection limits of l/600 are suggested to prevent serviceability issues during construction. Methods for determining deflection of reinforced masonry beams are examined, with recommending using an effective moment of inertia approach. A span limit of l/d=8 is proposed where deflections do not need to be checked.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Evaluation of green concrete types
- 1. Featured at the XVIII Symposium on Nordic Concrete Research, Helsingør, June 2002 Evaluation of Green Concrete Types Mette Glavind Head of section, M.Sc., Ph.D. Concrete Centre, Danish Technological Institute Gregersensvej, 2630 Taastrup, Denmark mette.glavind@teknologisk.dk Marianne Tange Jepsen M.Sc., Ph.D. student Concrete Centre, Danish Technological Institute ABSTRACT The goal of the Centre for Green Concrete is to reduce the environmental impact of concrete. Mix designs and results of different green concrete types are shown. Fulfilment of environmental goals is indicated by an example of a life cycle screening of a bridge column. Key words: CO2, residual products, green concrete, mix design, life cycle screening. 1. INTRODUCTION In Denmark a centre for Resource Saving Concrete Structures (short name Centre for Green Concrete) is formed with the aim of reducing environmental impact from concrete. To enable this, new technology is developed. The technology considers all phases of a concrete construction’s life cycle, i.e. structural design, specification, manufacturing, maintenance, and it includes all aspects of performance. An overview of the centre is given in /1/. In this article an evaluation is given on the different investigated green concrete types. 2. FOUR WAYS TO PRODUCE GREEN CONCRETE Four ways to produce green concrete are being investigated. 1. To increase the use of conventional residual products, i.e. fly ash in large quantities. 2. To use residual products from the concrete industry, i.e. stone dust (from crushing of aggregate) and concrete slurry (from washing of mixers and other equipment). 3. To use residual products from other industries not traditionally used in concrete, i.e. fly ash from bio fuels and sewage sludge incineration ash (from sewage treatment plants). 4. To use new types of cement with reduced environmental impact (mineralised cement, limestone addition, waste-derived fuels). The concrete types selected for testing are shown below for concrete in passive (P) and aggressive (A) environmental class, respectively. It can be seen that the four principles of producing green concrete are combined in order to achieve the most environmentally friendly concrete. All the concrete types fulfil the technical goals described in /1/.
- 2. 2 PR Reference concrete P2 50% fly ash and 10% kiln dust of powder P3 17% sewage sludge incineration ash of powder P5 Concrete slurry P6 100% stone dust of sand P7 30% fly ash from bio fuels of powder AR Reference concrete A0 Cement with reduced environmental impact A1 40% fly ash of powder and cement with reduced environmental impact A3 10% sewage sludge incineration ash of powder and cement with reduced environmental impact. A5 Concrete slurry A6 50% stone dust of sand 3. PRELIMINARY RESULTS Results from investigation of mechanical properties of a green concrete show that these do not differ significantly from the mechanical properties of the reference concrete, see /2/. Results from investigation of workmanship show that some of the green concrete may lose workability more quickly than the reference concrete, be more adhesive or require a longer resting time before finishing can begin. It is expected that some of these problems can be solved by optimising the type and the amount of chemical admixtures. An evaluation of the practical aspects seen from the concrete manufacturers point of view is seen in /3/. It seems possible to produce these types of green concrete, which is just as durable as conventional concrete, /4/. It is difficult to obtain a satisfactory air void structure for the concrete with large quantities of fly ash for aggressive environmental class (A1). When the correct mix design has been achieved, an expanded control at the manufacturing site is needed. Concrete with sewage sludge incineration ash (P3 and A3) has been subjected to further investigations than the other green concrete types because the P3 showed lower compressive strength. No explanation for this has been found yet. Because of the high P2O5 content in the sewage sludge incineration ash it can not be rejected that a new durability problem or deterioration problem might occur. 4. LIFE CYCLE SCREENING The environmental goals, see /1/, are valid for the whole life cycle of a concrete structure and not for the concrete mix design. Therefore, life cycle screening will be carried out with the Demonstration Bridge as an example. A preliminary study has been performed for a bridge column made of three different design principles compared to a reference principle. An example of a result is shown in figure 1 for sources of CO2 emission in the life cycle. Column R is a reference column. Column A is a column with a green concrete type (A1). Column B is a column with stainless steel reinforcement and column C is a column with a permanent stainless steel cladding that replaces traditional shuttering. The lifetime is 50 years for all columns.
- 3. 3 Figure 1 Sources of CO2 emission for four types of columns It can be seen that the CO2 goal of 30% reduction is achieved for all three green columns. It can also be seen that concrete raw materials and repair are the main sources to the CO2 emission. 5. CONCLUSION The results obtained by the Danish Centre for Green Concrete show that it is possible to produce green concrete types where the properties such as durability, workmanship and mechanical properties are just as good as for ordinary concrete. An example of a life cycle screening of selected concrete types used in a bridge columns indicate that the environmental goals set up in the centre are fulfilled. REFERENCES 1.
