Cement is one of the most important constituents of concrete. Most of the properties of concrete depend on cement. Cement is manufactured by calcining argillaceous and calcareous materials at a high temperature. During this process, large amount of CO2 is released in to the atmosphere The properties of materials for cement, fine aggregate, coarse aggregate, sand with M-sand were studied for mix design. The various strength of concrete like compressive, split tensile, flexural were studied for various replacement of fine aggregate using sand with M-sand that are 0%,20%, and 40%.Dolomite powder has some similar characteristics of cement. Using dolomite powder in concrete can reduce the cost of concrete and may increase the strength to some extent. and cement with Dolomite powder in cement concrete. The replacement percentages tried were 0%, 20%, and 40% by weight of cement. The results indicate that replacement of cement with dolomite powder increases the compressive, split tensile and flexural strengths of concrete.
Key words: Dolomite Powder, Compressive strength, Split tensile strength, flexural strength.
