Modified superfine slag micro-powder with effect of concrete wear resistance improving, and preparation method thereof
The invention relates to modified superfine slag micro-powder with an effect of concrete wear resistance improving, wherein the modified superfine slag micro-powder is prepared from the following raw materials by weight: 950-960 parts of slag, 40-45 parts of waste porcelain powder, 0.1-0.5 part of triethanolamine, 0.1-0.3 part of triisopropanolamine, 0.2-0.4 part of sodium oleate, 0.5-0.8 part of nanometer polytetrafluoroethylene, 80-100 parts of desulfurization gypsum, 0.1-0.3 part of triethanolamine sulfate salt, and 0.3-0.5 part of molasses. According to the present invention, the triethanolamine, the triisopropanolamine, the sodium oleate, the triethanolamine sulfate salt and the molasses are used, such that the residual charge on the micro-fine powder surface can be shielded, the Si-O bond cleavage in the slag can be promoted, the micro-fine powder aggregation can be prevented, and the grinding efficiency and the micro-powder fineness can be improved; the nanometer polytetrafluoroethylene is used, such that the surface energy is reduced, the particle agglomeration is prevented, the dispersibility of the micro-powder can be improved; and the waste porcelain powder is used, such that the grinding efficiency is improved, and the wear resistance and the hardness of the concrete are improved.
