Soil stabilizer and preparation method thereof
The invention provides a soil stabilizer which is prepared from the following raw materials in parts by weight: 5-20 parts of sulphoaluminate cement, 5-10 parts of Portland cement, 20-60 parts of mineral powder, 15-45 parts of gypsum, 3-5 parts of quick lime, 1-2 parts of sodium silicate, 1-2 parts of an expanding agent and 1-2 parts of a retarder. The expanding agent is one or more of lauryl sodium sulfate, fatty alcohol polyoxyethylene ether sodium sulfate, alkylphenol polyoxyethylene ether and fatty alcohol ammonium sulfate; the retarder is any one of glucose, starch, sodium hexametaphosphate, lignosulfonate and sodium citrate. The soft soil curing agent has the beneficial effects that the setting time of the soft soil curing agent is short, and the treated cured soil has the characteristics of fast strength development, micro-expansion in volume, better durability and the like. The method is particularly suitable for treatment of foundation soft soil, and is also suitable for soft soil reinforcement and treatment in low-temperature environment, and the solidified soil can have better mechanical properties and durability, so that the stability of a roadbed and the foundation is improved.
本发明提出了一种土壤固化剂，其由下列重量份的原材料组成：硫铝酸盐水泥5～20份，硅酸盐水泥5～10份，矿粉20～60份，石膏15～45份，生石灰3～5份，硅酸钠1～2份，膨胀剂1～2份，缓凝剂1～2份；膨胀剂为十二烷基硫酸钠、脂肪醇聚氧乙烯醚硫酸钠、烷基酚聚氧乙烯醚、脂肪醇硫酸铵中的一种或几种；缓凝剂为葡萄糖、淀粉、六偏磷酸钠、木质磺酸盐、柠檬酸钠中的任一种。本发明的有益效果如下：软土固化剂凝结时间短，处理的固化土具有强度发展快，体积微膨胀，耐久性较好等特点。特别适用于地基软土的处理，也适用于低温环境下施工的软土加固和处理，可使固化土具有较好的力学性能和耐久性，以提升路基和地基的稳定性。
