    Effect of Replacement of Cement with Dolomite Powder

    Dolomite powder obtained by powderising the sedimentary rock forming mineral dolostone can be used as a replacement material for cement in concrete up to certain percentage. 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. This

    Replacement of cement with dolomite powder is found to improve the strength of concrete. The maximum replacement percentage of cement with dolomite powder is found to be 5% and at this replacement level, the maximum increase in the 28th day compression and flexural strength were found to be 5.84% and 2.73% respectively

    that the addition of dolomite in powder form to cement performs a comparable compressive strength to Portland-limestone cement [1,2]. Moreover, similar to limestone, dolomite may be involved in hydration of cement, resulting in the formation of carboaluminates and the stabilization of ettringite. Besides, Mg released from dolomite is considered to interact with the cement
