Environment-friendly curing agent for curing soft soil as well as preparation method and application of environment-friendly curing agent
The invention relates to the technical field of soft soil foundation reinforcement, in particular to an environment-friendly curing agent for curing soft soil and a preparation method and application of the environment-friendly curing agent. The invention provides an environment-friendly curing agent for curing soft soil, which comprises the following components in percentage by weight: 70-100% of cement, 3-4% of gypsum, 5-15% of blast furnace slag, 5-15% of mineral powder, 1-3% of high-molecular polymerization catalyst and 3-7% of calcium bentonite, and the sum of the weight percentages of the components is 100%. The macromolecular polymerization reaction catalyst is prepared from calcium lignosulphonate, triethanolamine and sodium polyacrylate; the macromolecular polymerization reaction catalyst adopts a composition of calcium lignosulphonate, triethanolamine and sodium polyacrylate, the consistency of the curing agent is improved through the synergistic effect of the calcium lignosulphonate, the triethanolamine and the sodium polyacrylate, the unconfined compressive strength of cement soil formed by curing soft soil through the curing agent is high, and the problem of guniting blockage is not prone to being generated in the construction process.
本发明涉及软土地基加固技术领域，特别涉及一种用于固化软土的环保型固化剂及其制备方法和应用。本发明提供了一种用于固化软土的环保型固化剂，按重量份数计，包括以下组分：水泥70％～100％，石膏3％～4％，高炉矿渣5％～15％，矿粉5％～15％，高分子聚合反应催化剂1％～3％，钙基膨润土3％～7％，以上各组分的重量百分比之和为100％，所述高分子聚合反应催化剂包括：木质素磺酸钙、三乙醇胺与聚丙烯酸钠；本发明中的高分子聚合反应催化剂采用木钙、三乙醇胺和聚丙烯酸钠的组合物，三者协同作用，改善了固化剂稠度，该固化剂用于固化软土形成的水泥土的无侧限抗压强度高，且在施工过程中不易产生喷浆阻塞问题。
