Abstract
The use of calcium carbonate and fly ash in concrete has not been a common practice due to number of reasons. Recently after the technological developments fly ash is been used in preparing the concrete. A wide variety of RMC’s mow use fly ash in preparing concrete. The use of fly ash and calcium carbonate in concrete lead to many environmental benefits as the waste material can be used in concrete and hence no issues of dumping waste into the environment. It proves economical as the cost of concrete is reduced. In my study the use of calcium carbonate and fly ash in concrete was taken and cement of grade OPC 43 was used. The cement was replaced in concentrations of 5%, 10%, 15%, 20%, 25%, 30% by fly ash ash and calcium carbonate simultaneously. The optimum concentration of fly ash , calcium carbonate and mixture of fly ash and calcium carbonate was 20%, 15%, 10% F.A 5% CC simultaneously.
