Soil stabilizer and preparation method thereof

The invention discloses a soil curing agent, which is prepared from the following components in parts by mass: 60 to 70 parts of calcium hydroxide, 1 to 10 parts of nanoscale silicon dioxide, 15 to 20 parts of SiO2, 8 to 11 parts of Al2O3, 0.5 to 1 part of FeO, 2 to 3 parts of Fe2O3, 0.8 to 1.2 parts of CaO, 0.2 to 0.5 part of MgO, 0.2 to 0.6 part of K2O, 0.05 to 0.1 part of SO3, 0.1 to 0.2 part of sulfate, 2 to 5 parts of silicate, 2 to 8 parts of performance additive, 0.5 to 1 part of cross-linking agent and 6 to 8 parts of deionized water. The soil stabilizer disclosed by the invention is suitable for soil with the water content of less than 15%, the setting time of concrete can be prolonged, the construction time of 2-3 days is provided, and the cured soil is high in compressive strength and strong in water resistance. The soil stabilizer disclosed by the invention is simple in preparation process, safe, environment-friendly and good in comprehensive performance. 本发明公开了一种土壤固化剂，按质量份计，所述固化剂包括60-70份氢氧化钙、1-10
