Water-proof ultra-fine slag powder and preparation method thereof
The invention discloses water-proof ultra-fine slag powder. The water-proof ultra-fine slag powder is prepared from the following raw materials in parts by weight: 950 to 960 parts of slag, 35 to 40 parts of glassy carbon, 0.1 to 0.5 part of triethanolamine, 0.1 to 0.3 part of triisopropanolamine, 0.4 to 0.6 part of hydrophobic type dispersible adhesive powder, 0.5 to 0.8 part of nano polyetrafluoroethylene, 80 to 100 parts of desulfurization gypsum, 0.1 to 0.3 part of barium laurate and 0.3 to 0.5 part of sebacic acid. According to the water-proof ultra-fine slag powder disclosed by the invention, by using the triethanolamine, the triisopropanolamine, the desulfurization gypsum, the barium laurate and the sebacic acid, residual charge on the surface of fine powder can be shielded, the Si-O bond breakage in the slag can be promoted, and the coalescence of the fine powder is prevented; by using the nano polyetrafluoroethylene, the surface energy is reduced, particle aggregation is prevented, and the dispersity of the fine powder can be increased; by using the glassy carbon and the hydrophobic type dispersible adhesive powder, the grinding efficiency and the fineness of the fine powder are increased, and the water resistance of concrete can also be increased.
