High-dosage fluorgypsum-based multi-element solid waste filling cementing material and preparation method thereof
The invention discloses a high-dosage fluorgypsum-based multi-element solid waste filling cementing material and a preparation method thereof, the cementing material is formed by homogenizing and mixing 50 wt%-75 wt% of fluorgypsum, 4 wt%-10 wt% of carbide slag, 14 wt%-38 wt% of granulated blast furnace slag and 1 wt%-3 wt% of a modifier, and the modifier is formed by compounding sulfates, sodium methyl silicate and water glass. Compared with a cement cementing material, the cementing material disclosed by the invention shows better filling performance, not only has high early strength and low filling cementing material cost, but also has the advantages that the later strength is not attenuated, and the cementing material also shows a better mine underground water corrosion resisting effect.
本发明公开了一种大掺量氟石膏基多元固废充填胶凝材料及其制备方法,所述胶凝材料由50wt%~75wt%的氟石膏、4wt%~10wt%的电石渣、14wt%~38wt%的粒化高炉矿渣和1wt%~3wt%的改性剂均化混合而成,其中,改性剂由硫酸盐类与甲基硅酸钠和水玻璃复配而成。本发明的胶凝材料与水泥胶凝材料相比,表现出更好的充填性能,不仅早期强度高,充填胶凝材料成本低,而且具有后期强度不衰减、亦表现出较好抗矿井地下水腐蚀效果。
