Concrete is a blender of cement, fine agg, coarse agg and water. Propelled solid innovation increasingly improved to the solid properties like quality, strength, functionality, stream capacity. This paper is on new and solidifying property of cements made with m sand. The test concentrates on Mechanical Strength properties. In this investigation fractional supplanting of Cement with dolomite at 0%, 15%,30%,45% and supplanting characteristic sand with Manufactured sand. The mechanical properties of cement for example compressive quality, split Tensile quality are concentrated of cement made with substitution of dolomite and M sand and results are contrasted and traditional cement. In this work M40 grade solid blend and normal of three examples were tried for 7 days and 28days.
