Experimental investigation on significance of energy efficient materials in enhancing compressive strength property of concrete Available to Purchase

The generation of waste materials have increased, which has to dispose these materials into landfills. The disposal of such waste materials causing scarcity of land and also increases health-related issues for the surrounding residents. Alternative and sustainable solution to dumping of waste materials is the utilization of these waste materials in the production of concrete. To reduce energy consumption in construction, partial replacement of energy efficient material to be added concrete. Therefore, the energy efficient material chosen was rice husk ash replaced for cement, partial replacement of GGBS as fine aggregate and demolished waste replaced for coarse aggregate. The material properties were carried out for the concrete constituents and energy efficient material. The mix was designed by IS code method. The work was conducted on grade M30. The fresh concrete tests were conducted. The normal concrete sample casted for the ages of 7 and 28 to calculate the characteristics compressive strength. The cubes were casted with rice husk ash (RHA) as replaced partly in cement by weight at 10%,15%,20%. The optimum replacement of 15 % RHA in cement is determine. The fine aggregate is partly replaced by GGBS and optimum % of RHA with various % of 5%,10% and 15% GGBS added to the concrete. The optimum % of RHA with various % of GGBS is taken as 15%. The coarse aggregate is partially replaced by demolished waste and optimum % of rice husk ash & GGBS with various % of 10%,15% and 20% of demolished waste was added to the mixture of concrete and the optimum % of rice husk ash & GGBS with various% of demolished waste is found to be 10%.
