ABSTRACT: In this Evalution the cement mortars cube with compound of ordinary Portland cement (OPC) and Ground Granulated Blast Furnace Slag (GGBS) and Metakaolin (MK) replacement levels. So the cement has been partially replaced by GGBS and Metakaolin in the order of 0%, 5%, 10%, 15%, 20%. So this result is confess a individual compressive strength (at ages of 3, 7, 14, 28, days) of cement mortar. Compressive Strength increased upto 40% by using Metakaolin & GGBS. Cement mortars cubes with the combinations of GGBS and Metakaolin communicate stronger development in strength and durability.
