Borosilicate glass powder modified ultra-fine slag micro-powder and preparation method thereof
The invention provides borosilicate glass powder modified ultra-fine slag micro-powder which is prepared from the following raw materials in parts by weight: 950-960 parts of slag, 30-35 parts of borosilicate glass powder, 0.2-0.4 part of triethanolamine, 0.1-0.3 part of triisopropanolamine, 0.2-0.4 part of myristic-hydroxy hydrotalcite, 0.5-0.8 part of nano polytetrafluoroethylene, 80-100 parts of desulfurization gypsum, 0.1-0.3 part of flake caustic soda, 0.3-0.5 part of tung oil and 0.2-0.3 part of ammonium bicarbonate. By using nano polytetrafluoroethylene, the surface energy of the slag micro-powder provided by the invention is reduced, particle aggregation is prevented, and the dispersibility of the micro-powder can be improved; and by using the borosilicate glass powder, the expansion ratio of concrete can be reduced, and the high temperature resistance, strength and hardness of the concrete can be increased.
