Concrete is the most widely used construction material in civil engineering construction because of its goodcompressive strength and stability. Concrete industry is now looking for the supplementary cementitious materials andthe industrial by-products with the objectives to reduce the CO2 emission which is harmful to the environment. Dolomitepowder is one of the suitable supplementary cementitious materials, which is obtained by powdering the „Dolostone„mineral. Present investigations are carried out to study the feasibility of applications of Dolomite powder in effectivemanner to replace cement partially in concrete. Presently, the mechanical properties of M30 grade concrete are studiedwith the partial replacement of cement by Dolomite powder which ranges from 0 to 25 percent. The optimum Dolomitepowder percentages in concrete to ascertain maximum compressive strength as well as tensile strength were determined.Keeping the optimum percentage dosage of Dolomite as constant in referred concrete, cement is further replaced withGGBS percentage which ranges from 5 to 20 percent. Test results reveal that the maximum strength (compressive andtensile) were attained for the mix with 10 % Dolomite powder in combination with 10% GGBS powder as partialreplacement of cement.
