Curing agent for rapidly curing waste slurry by using modified magnesium phosphate cement and preparation method of curing agent
The invention discloses a curing agent for rapidly curing waste slurry by using modified magnesium phosphate cement and a preparation method of the curing agent, and belongs to the technical field of building materials, and the method can be used for treating the waste slurry produced in civil engineering construction and tunnel engineering. The curing agent comprises the following components in parts by mass: 8-12 parts of magnesium phosphate cement, 6-8 parts of quick lime, 6-8 parts of blast furnace slag and 4-6 parts of sodium silicate. Compared with the prior art, the magnesium phosphate cement is modified, so that the cured waste slurry has higher strength. According to the invention, by mixing and stirring with the waste slurry and curing for 3d, 7d, 14d and 28d, a large amount of hydration gelling products are formed through a series of hydration reactions, so that on one hand, industrial solid wastes such as blast furnace slag and the price of a quick lime material are low, and the curing treatment cost is reduced; and on the other hand, the strength and water resistance of the waste slurry solidified soil body are improved, so that the strength is quickly improved in a short time, and the water erosion resistance is better.
本发明公开一种改性磷酸镁水泥快速固化废弃泥浆的固化剂及其制备方法，属于建筑材料技术领域，该方法可以处理土木工程施工、隧道工程中产的废弃泥浆。固化剂按照质量份数计，包括如下组分：磷酸镁水泥8～12份、生石灰6～8份、高炉矿渣6～8份，硅酸钠4～6份。与现有技术相比，本发明将磷酸镁水泥改性，使其固化废弃泥浆具有更高的强度。本发明通过与废弃泥浆进行混合搅拌，固化时间为3d，7d，14d，28d经过一系列水化反应形成大量的水化胶凝产物，一方面消耗了高炉矿渣这类工业固体废料和生石灰材料价格的便宜，降低了固化处理的成本，另一方面改善了废弃泥浆固化土体的强度和耐水性，使其强度在短期内快速提升和抵抗水的侵蚀能力更好。
