Hardener for improving stability of tailing slurry as well as preparation method and use method of hardener
The invention relates to a hardening agent for improving the stability of tailing slurry as well as a preparation method and a use method of the hardening agent, and belongs to the technical field of geotechnical engineering. The hardening agent for improving the stability of the tailing slurry comprises the following components in percentage by mass: 6-8% of ferrous sulfate crystals, 12-16% of hydrogen peroxide, 5-10% of fly ash, 0.1-0.2% of cationic polyacrylamide, 10-15% of quick lime, 10-20% of cement and the balance of water. According to the hardening agent, the hardening degree of the tailing slurry can be greatly improved, volume reduction and weight reduction are achieved, storage is easy, the hardness of the tailing slurry treated through the hardening agent is far higher than that of untreated tailing slurry, the tailing slurry is denser and not prone to deformation, and the strength of the hardened slurry can be kept for a long time.
本发明涉及一种用于提高尾矿泥浆稳定性的硬化剂及其制备方法和使用方法,属于岩土工程技术领域。该用于提高尾矿泥浆稳定性的硬化剂包括以下质量百分数的组分:硫酸亚铁晶体6~8%、双氧水12~16%、粉煤灰5~10%、阳离子聚丙烯酰胺0.1~0.2%、生石灰10~15%和水泥10~20%,其余为水。本发明的硬化剂可以使尾矿泥浆硬化程度大幅提高,且减容减量易于储存,经本发明的硬化剂处理后的尾矿泥浆其硬度远高于未处理的尾矿泥浆,且更加密实不易变形,能够长期保持硬化处理后矿泥的强度。
