Effect of dolomite powder on the hydration and

2019-9-23 · Dolomite CaMg(CO3)2 is an abundant carbonate mineral, and it frequently coexists with calcite in nature. Unlike limestone, dolomite is currently not accepted as a filler or component of cement because some forms of dolomite aggregates might cause concrete damage due to the dedolomitization. However, it has already been reported 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
