High-impermeability curing agent for sandy soil and preparation method of high-impermeability curing agent
The invention discloses a high-impermeability curing agent for sandy soil and a preparation method, the high-impermeability curing agent comprises the following components by mass: 30-50 parts of a solid waste-based sulfur aluminum iron series cementing material; 10 to 30 parts of slag powder; 5-30 parts of ordinary Portland cement; 5-20 parts of desulfurized gypsum; and 1-10 parts of silica fume. A curing agent system further strengthens the hydration effect and the cementing performance of the cementing material, and a formed crystal-colloid composite hydration product system contributes to the stable and compact microstructure of the cured sandy soil, so that the impermeability and the mechanical property of the sandy soil can be greatly improved; the comprehensive application of solid waste raw materials such as desulfurized gypsum and mineral powder is realized, and the stacking cost of solid wastes and the influence on the environment are reduced.
本发明公开了一种用于砂质土的高抗渗固化剂及制备方法，高抗渗固化剂，按质量份计，由以下组分组成：固废基硫铝铁系胶凝材料30‑50份；矿渣粉10‑30份；普通硅酸盐水泥5‑30份；脱硫石膏5‑20份；硅灰1‑10份。固化剂体系不仅进一步强化了胶凝材料的水化作用和胶结性能，且所形成的晶体‑胶体复合水化产物体系将贡献于固化砂土的稳定及致密的微结构，可以极大地提高砂土的抗渗性及力学性能；实现脱硫石膏，矿粉等固废原料的综合应用，减少固体废弃物的堆积成本和对环境造成的影响。
