Effect of the usage of calcite powder and diatomite powder as partial replacement with cement on the compression and split tensile strength of concrete

Abstract

Diatomite powder continent amorphous silica and pozzolanic material. Calcite powder is natural form of
calcium carbonate. This paper described the procedure and result of a laboratory investigation of mechanical properties
carried out on concrete specimen containing diatomite powder and calcite powder as partial replacement of cement in
concrete. Preparation of concrete specimens with diatomite powder and calcite powder with different ratio by volume as
replacement with cement. Find the best compressive strength and split tensile strength from the replacement of cement
with diatomite powder and calcite powder separately and together. Test result indicate that the concrete specimens
containing 10% diatomite powder and 10% calcite powder replacement by volume with cement separately and together
improve the compression and split tensile strength of the conventional concrete mixture.
