Mudstone hydrophobically modified grouting material and preparation method thereof
The invention discloses a mudstone hydrophobically modified grouting material and a preparation method thereof, and belongs to the technical field of underground engineering safety. The hydrophobically modified grouting material is prepared from, by weight, 40-50 parts of ordinary Portland cement, 5-10 parts of water-quenched slag, 10-20 parts of coal gangue powder, 2-3 parts of a water reducing agent, 50-70 parts of a surfactant solution and 5-8 parts of water glass. All the components are mixed in sequence to prepare the grouting material. The grouting material can enhance the water resistance of mudstone surrounding rock, reduce the water absorption expansion of the surrounding rock, improve the filling effect and enhance the compression resistance, and meanwhile, the influence of industrial solid wastes on the environment is reduced by utilizing the water-quenched slag and the coal gangue powder.
本发明的一种泥岩疏水改性的注浆材料及其制备方法，属于地下工程安全技术领域。所述疏水改性的注浆材料由以下重量份配比的原料制成：普通硅酸盐水泥40～50份、水淬渣5～10份、煤矸石粉10～20份、减水剂2～3份，表面活性剂溶液50～70份，水玻璃5～8份。各成分按顺序先后进行混合，即可制得注浆材料。该注浆材料可以增强泥岩性围岩的抗水性，减少围岩吸水膨胀，提高填充效果，增强抗压性能，同时利用水淬渣和煤矸石粉减少工业固体废物对环境的影响。
