Bi-component dry powdery geopolymer grouting material based on all-solid waste and preparation method of bi-component dry powdery geopolymer grouting material
The invention relates to a bi-component dry powder geopolymer grouting material based on all solid wastes and a preparation method thereof, and belongs to the technical field of grouting/filling materials, the bi-component dry powder geopolymer grouting material is composed of a dry powder material of a component A and a dry powder material of a component B. The component A comprises slag, a composite activator, a water reducing agent and an accelerator according to a mass ratio of 100: 4-8: 0.075-0.125: 0.6-1.8; and the component B is composed of desulfurized gypsum, fly ash, metakaolin, quick lime, a retarder and a water reducing agent in a mass ratio of (50-60): (20-30): (10-20): (5-8): (0.2-0.5): (0.05-0.1). The multi-source solid waste with a synergistic excitation effect is also used as a base material and an excitation material of the grouting material, the dosage of industrial raw material additives is greatly reduced, the reutilization rate and reutilization types of the solid waste are increased, and the grouting material belongs to a cement-free environment-friendly grouting material and meets the requirements of grouting treatment of deep engineering disasters, especially large-deformation disasters.
基于全固废的双组分干粉状地质聚合物注浆材料及其制备方法，属于注浆/充填材料技术领域，由A、B两种组分干粉材料构成，A组分组成及质量比：矿渣：复合激发剂：减水剂：速凝剂＝100：4～8：0.075～0.125：0.6～1.8；B组分组成及质量比：脱硫石膏：粉煤灰：偏高岭土：生石灰：缓凝剂：减水剂＝50～60：20～30：10～20：5～8：0.2～0.5：0.05～0.1。利用具备协同激发效应的多源固态废弃物兼做注浆材料基料和激发材料，大量减少工业原料外加剂用量，增加固废物的再利用率和再利用种类，属于无水泥环保型注浆材料，满足深部工程灾害特别是大变形灾害注浆治理的需求。
