In this paper study the experimental investigation of partial replacement of fly ash, lime, metakaolin by the weight of cement. It can increase the strength of concrete. The replacement of pozzolanic material various percentages of 0, 5, 10, 15, 20, 25, 30 by cement content. The preliminary test is conducted in the cementitious material such as fly ash, lime, metakaolin for specific gravity, fineness test, soundness test, and setting time of cement to check that having cementitious properties and then conducted the strength test of harden concrete like compressive strength, flexural strength, and split tensile strength test.
