Magnesium oxychloride-based soil stabilizer and application thereof
The invention discloses a magnesium oxychloride-based soil stabilizer and application thereof, the magnesium oxychloride-based soil stabilizer comprises 100-150 parts of light calcined magnesia powder, 50-260 parts of magnesium chloride solution, 0.1-1.0 part of toughening fiber, 0.3-1.0 part of enhanced water repellent agent and 0.3-0.7 part of anti-efflorescence agent, and the magnesium oxychloride-based soil stabilizer is characterized in that the enhanced water repellent agent is sodium hexametaphosphate; the anti-efflorescence agent is a vinyl chloride-vinylidene chloride copolymer emulsion. According to the magnesium oxychloride-based soil stabilizer and the application thereof, by-products of salt production are effectively utilized, the used raw material magnesium chloride is derived from an end product of salt production and is a by-product obtained after NaCI, KCI and bromine are extracted after seawater concentration, the liquid is used as a raw material to produce a novel building material, and recycling is realized; according to the invention, MgO, MgCI2 and H2O are utilized to enhance the solidification and gelling effects of a quaternary system of the water repellent agent, the purpose of utilizing waste and solid waste is achieved, and the solidification principle of the water repellent agent is MgO + MgCI2 + H2O-> 5Mg (OH) 2. MgCI2. 8H2O (5. 1. 8) crystal phase.
本发明公开了一种氯氧镁基土壤固化剂及其应用，包括轻烧氧化镁粉100‑150份，氯化镁溶液50‑260份，增韧纤维0.1‑1.0份，增强抗水剂0.3‑1.0份，抗返卤剂0.3‑0.7份，其特征在于：所述的增强抗水剂为六偏磷酸钠；所述的抗返卤剂为氯偏乳液。该氯氧镁基土壤固化剂及其应用，本发明将制盐的副产品进行有效利用，所使用的原材料氯化镁来源于制盐的末端产品，是海水浓缩后提取NaCI、KCI和溴素之后的副产品，利用该液体作原材料，生产新型建筑材料，即实现了可循环利用，又减少了对土壤、大气环境的危害，本发明利用MgO、MgCI2、H2O增强抗水剂四元体系的固结胶凝作用，达到本发明利废固废的目的，本发明的固化原理为：MgO+MgCI2+H2O→5Mg(OH)2·MgCI2·8H2O(5·1·8)结晶相。
