Premixed flow state solidified soil doped with high-silicon iron tailings and preparation method of premixed flow state solidified soil
The invention belongs to the field of civil engineering materials, and particularly relates to premixed flow-state solidified soil doped with high-silicon iron tailings and a preparation method of the premixed flow-state solidified soil. The premixed flow-state solidified soil doped with the high-silicon iron tailings is prepared from the following raw materials in parts by mass: 1-2 parts of lime, 2-5 parts of iron tailing powder, 12-15 parts of graded soil, 2-3 parts of water and 0.02-0.05 part of grinding aid. According to the premixed flow-state solidified soil provided by the invention, foundation pit excavation spoil is fully utilized, after a curing agent and water in a certain proportion are mixed, sufficient mixing is performed through a special machine, and a pumpable and flowable reinforcing material is formed and used for backfill pouring of various foundation pits and mining pits; meanwhile, the solidified soil can be widely applied to the field of reinforcement treatment of road roadbeds, building foundations and the like, use of high-energy-consumption resources such as cement and lime is effectively reduced, and energy consumption and carbon dioxide emission are reduced; meanwhile, a large amount of industrial solid waste is applied, and solid waste storage is reduced.
本发明属于土木工程材料领域，具体涉及一种掺有高硅型铁尾矿的预拌流态固化土及其制备方法。掺有高硅型铁尾矿的预拌流态固化土，按质量份计由以下原料组成：石灰1‑2份、铁尾矿粉2‑5份、级配土壤12‑15份、水2‑3份、助磨剂0.02‑0.05份。本发明提供预拌流态固化土充分利用基坑开挖弃土，在掺入一定比例的固化剂、水之后，通过特殊机械进行充分拌合，形成具有可泵送的、流动性的加固材料，用于各类基坑、矿坑的回填浇筑，同时可以广泛用于道路路基、建筑物地基等加固处理领域，有效减少水泥石灰等高能耗资源的使用，减少能源消耗和二氧化碳排放；同时应用大量工业固废，降低固废垃圾的存储。
