MODIFIED DOLOMITE POWDER, PREPARATION METHOD THEREOF AND CONCRETE
The invention provides a modified dolomite powder, a preparation method thereof, and a concrete. The modified dolomite powder is prepared from 98% to 99% of a dolomite powder, 0.2% to 0.5% of a chaotropic agent, 0.6% to 1.0% of a dihydrogen phosphate, and 0.2% to 0.5% of a capillary filler according to the mass percentage. The chaotropic agent is one or more of sodium sulfate, potassium sulfate, and ammonium sulfate. By promoting the dissolution of the surface of the dolomite powder, participating in the hydration reaction, and filling capillary pores, the triple modification solves the problems of bleeding, strength, and durability of the dolomite powder concrete in the related art. The obtained modified dolomite powder has good solubility and high chemical activity, and the prepared concrete has high strength and compactness, low porosity, and good durability.
