Influences of the dosage of dolomite powder on the fracture properties and volume stability of cement-based materials

The effects of dolomite powder dosage on the fracture properties and volume stability of cement-based materials were investigated by three-point bending method and corrugated tube method, respectively. The experiment results showed that the fracture toughness of cement mortar incorporating dolomite powder was raised compared to that of reference cement mortar. After dolomite powder was added into cement paste, the improvement of fracture...
