Grouting filling material and preparation method thereof
The invention discloses a grouting filling material and a preparation method thereof. The grouting filling material comprises water, Portland cement, loess and water glass. The strength development of the grouting filling material is fast, the slurry volume filling and the strength development have good coordination, and the invalid diffusion of the slurry in the range outside the goaf is effectively reduced while the grouting fluidity is met; in addition, the grouting material is wide in source, the filling efficiency is high, and the grouting cost is greatly reduced. Therefore, the defects that an existing goaf grouting material is high in drainage rate of different degrees, low in stone rate, poor in stability, high in cost, not ideal in filling effect and the like are overcome.
本发明公开了注浆充填材料及其制备方法，所述注浆充填材料包括：水、硅酸盐水泥、黄土和水玻璃。该注浆充填材料的强度发展快、浆体体积充填和强度发展具有良好的协调性，在满足注浆流动性的同时，有效减少了浆液在采空区以外范围的无效扩散；另外，注浆材料来源广泛，填充效率高，大幅度降低了注浆成本。从而解决了现有采空区注浆材料存在不同程度析水率高、结石率低、稳定性差、成本高以及充填效果不理想等缺陷。
