摘要： 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.

摘要： An ultrastable cementitious material with nano-molecular veneer makes a cementitious material by blending 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide based on a final total weight of the cementitious material, with 14 wt % to 18 wt % of a magnesium chloride dissolved in water and reacting to form a liquid suspension, mixing from 2 to 10 minutes, adding a phosphorus-containing material, and allowing the liquid suspension to react into an amorphous phase cementitious material, wherein a portion of the amorphous phase cementitious material grows a plurality of crystals. The plurality of crystals are encapsulated by the amorphous phase cementitious material forming a nano-molecular veneer. A process to make the ultrastable cementitious material. A tile backer board incorporating the ultrastable cementitious material and a process for making the tile backer board.

摘要： Gypsum panels and methods of making the same are provided. A method of making a gypsum panel includes forming a first gypsum slurry by combining stucco, water, a siliconate, and a phosphate salt or polymer, and setting the first gypsum slurry to form at least part of a core of the gypsum panel, wherein the gypsum panel displays a 2-hour water absorption test weight increase of at least 10 weight percent less than an otherwise identical comparative panel containing no phosphate salt or polymer in its core.
