Flexible solid waste-based grouting material as well as preparation method and application thereof
The invention discloses a flexible solid waste-based grouting material and a preparation method and application thereof, and belongs to the technical field of mineral engineering grouting materials, the grouting material comprises 30.8-46.8% of fly ash, 8-24% of slag powder, 12-16% of gypsum, 8-16% of red mud, 1-10% of an alkaline calcium-based activator, 16-20% of a flexible component, and 0.1-0.25% of a water dispersion resistant component, the flexible material comprises acrylamide, a cross-linking agent and an initiator. The grouting material disclosed by the invention is a cementing material composed of all solid wastes, and the solid-waste-based cementing material formed by synergistic excitation on the basis of utilizing the physical and chemical properties of the solid wastes to the maximum extent has the advantages of low carbon, environmental protection and remarkable environmental benefits; in addition, the all-solid waste cementing material is wide in source, the material cost is far lower than that of a Portland cement-based grouting material, and the advantage of low cost is achieved; meanwhile, the toughening effect of the flexible material acrylamide is combined, and the prepared grouting material is a flexible material, so that the grouting material is applicable to roof reinforcement, stratum reinforcement and the like.
本发明公开了一种柔性固废基注浆材料及其制备方法和应用，属于矿业工程注浆材料技术领域，该注浆材料包括粉煤灰30.8～46.8％，矿渣粉8～24％，石膏12～16％，赤泥8～16％，碱性钙基激发剂1～10％，柔性组分16～20％，抗水分散组分0.1～0.25％，且所述柔性材料包括丙烯酰胺、交联剂和引发剂。本发明的注浆材料是一种全固废组成的胶凝材料，在最大化利用各固废物理化学属性的基础上，协同激发形成的固废基胶凝材料，具有低碳环保，环境效益显著的优势；另外全固废胶凝材料来源广泛，材料成本远低于硅酸盐水泥基注浆材料，具有成本低廉的优势；同时，结合了柔性材料丙烯酰胺的增韧效果，制备得到的注浆材料是一种柔性材料，从而适用于顶板加固以及地层加固等方面应用。
