Cement the main binding ingredient in concrete is becoming expensive and its production contributing to environmental pollution by emitting CO2 gases that are the main cause of global warming so efforts are being taken to utilize local natural or solid waste resources as a supplementary cementing material.RHA is a by-product of paddy industry, highly reactive pozzolana which is produced by burning rice husk at controlled temperatures. FA is collected from the combustion air-stream exiting the power plant. Fly ash is pozzolanic, which means it’s a siliceous or siliceous-and-aluminous material that reacts with calcium hydroxide to form a cement. WGP Glass is amorphous and contains a large amount of silicon and calcium. Thus it can be claimed that it is pozzolanic or even cementitious in nature even when it is finely ground, waste glass powder is formed from grinding industry by grinding waste glass obtained from lights bulbs, bottles and so on. The details of experimental investigations are done to study the effect of replacing a portion of cement with rice husk ash, fly ash and waste glass powder is reported in this paper. The main aim of this work is to determine the optimum percentage of RHA, FA, and WGP as a partial replacement of cement for the conventional grade of concrete and to study the strength variation in its percentage replacement with RHA, WGP, and FA. The studies conducted on cement concrete reveal that 10% RHA,5 and 5% WGP give optimum results for cement replacement in concrete.
