    communities, as that of cement the replacement of river sand is also very important. Therefore in the present study M30 grade of concrete is considered to replace cement, by Ground Granulated Blast furnace Slag (GGBS) and natural sand by Manufactured Sand. The cement is replaced by GGBS as 10%, 20%, 30%, 40% and 50% with M – sand.
