Geopolymer grouting material as well as preparation method and application thereof
The invention discloses a geopolymer grouting material and a preparation method and application thereof, potential activity of fly ash and slag is stimulated by an alkali activator to promote geopolymer reaction, pores are physically filled by limestone powder, chemical reaction nucleation sites are provided to promote product generation, and compactness of the grouting material is effectively improved. Compared with a traditional cement-based grouting material, the geopolymer grouting material is short in setting time, high in compressive strength and low in energy consumption and cost in the production process, the problem of waste of waste stone powder in the limestone processing process can be effectively solved, waste is turned into wealth, environmental protection is facilitated, and good economic and social benefits are brought.
本发明公开了一种地聚物注浆材料及其制备方法和应用，通过碱激发剂激发粉煤灰和矿渣的潜在活性，促使地聚合物反应发生，同时利用石灰石粉末物理填充孔隙，并提供化学反应成核位点以促进产物生成，有效提升了注浆材料的密实性。与传统的水泥基注浆材料相比，本发明的地聚物注浆材料凝结时间较短，抗压强度较高，生产过程中能耗和成本更低，还能有效解决石灰石加工过程中废弃石粉的浪费问题，实现变废为宝，有利于环境保护，并带来良好的经济和社会效益。
