Composite grouting material and preparation method thereof
The invention discloses a composite grouting material. Industrial waste residues such as fly ash, mineral slag and steel slag are used for replacing cement to serve as the grouting material, sodium ions cannot be lost to form an alkaline environment in a flowing water environment for a long time, and better durability of the composite grouting material is effectively ensured; the gel with a three-dimensional network structure is formed through interaction and cross-linking polymerization reaction among the acrylate, the cross-linking agent and the accelerant, the pore structure of the gel is small, and pore gaps formed by the mixed solution of the component A are filled with the gel, so that water flow cannot enter the pore structure, the waterproof effect is better, and then the stability is better. The method for preparing the composite grouting material provided by the invention solves the problems of poor durability and strength loss caused by disintegration of water glass in an alkaline environment due to easy loss of sodium ions when a grouting material water glass slurry material is soaked in a water environment for a long time in the prior art. The method is high in applicability, good in durability, remarkable in economic and social benefits and suitable for wide popularization.
本发明公开了一种复合注浆材料，使用粉煤灰、矿渣、钢渣等工业废渣代替水泥作为注浆材料，在长期处于动水环境下，不会流失钠离子形成碱性环境，有效保证了该种复合注浆材料更好的耐久性；通过丙烯酸盐、交联剂、促进剂之间相互作用，交联聚合反应形成三维网络结构的凝胶，凝胶的孔结构小，填充在A组分的混合液形成的孔缝隙中，使得水流不能进入孔结构，防水效果更佳，进而稳定性更好。本发明提供的一种制备复合注浆材料的方法解决现在技术所存在的注浆材料水玻璃浆材长期处于有水环境下浸泡时易钠离子流失，导致水玻璃在碱性环境下发生崩解，造成耐久性差，强度损失的问题。本发明适用性强、耐久性好、经济社会效益显著，适于广泛推广。
