The Marble Slurry Wastes (MSW) produced by marble industry is left unattended in the environment which causes serious environmental problems. In order to evaluate its potential usage in normal 1:2:4 concrete, this study was designed, where the partial replacement of cement with MSW was examined. Replacement of cement with MSW from 0 to 100%, and also its usage as an additive material 10% and 20% by weight of cement were the main objectives of this study. Various laboratory tests, like

... e strength test, splitting tensile test and slump test were conducted by using local available MSW. The primary chemical composition of the MSW indicated that it contains high contents, nearly 97% of lime (CaO). The laboratory results show that cement in structural concrete can be replaced by MSW up to 7% safely. The compressive and splitting tensile strength of concrete was observed to be increased by 15% and 6% by the addition of 10% MSW. A similarly increase in strength was also observed by adding the 20% of MSW additionally to the normal 1:2:4 concrete. However, by the addition of MSW in concrete, its slump strength i.e., its workability is found to be reduced.
