Heavy metal contaminated soil multi-solid-waste compound stabilizer and preparation method thereof
The invention relates to a heavy metal contaminated soil multi-solid-waste compound stabilizer and a preparation method thereof, and belongs to the technical field of ecological restoration. The heavy metal contaminated soil multi-solid-waste compound stabilizer comprises the following raw materials in parts by weight: 25-30 parts of aluminum slag, 10-20 parts of steel slag, 15-20 parts of rock powder, 10-15 parts of ordinary Portland cement, 6-10 parts of an exciting agent, 1-4 parts of an ion replacement agent, 2-4 parts of a water repellent, 5-8 parts of a retarder, 1-2 parts of an early strength agent, 2-4 parts of a strength retaining agent, 0.4-1 part of a water reducing agent, 1-1.5 parts of a humic acid modifier and 1-1.5 parts of a stabilizer. The soil stabilizer disclosed by the invention is simple in construction process, and easy to operate, solves the curing problem of the soil containing humic acid, greatly improves the performance indexes such as compactness, strength, durability and stability of the cured soil, and has good economic and environmental benefits.
本发明涉及一种重金属污染土壤多固废复合稳定剂及其制备方法，属于生态修复技术领域，包括以下重量份的原料：铝渣25‑30份、钢渣10‑20份、岩粉15‑20份、普通硅酸盐水泥10‑15份、激发剂6‑10份、离子替换剂1‑4份、憎水剂2‑4份、缓凝剂5‑8份、早强剂1‑2份、保强剂2‑4份、减水剂0.4‑1份、腐殖酸改性剂1‑1.5份、稳定剂1‑1.5份，本发明的土壤固化剂施工工艺简单，易于操作，解决了含有腐殖酸土壤的固化问题，极大的提高了固化土密实度、强度、耐久性和稳定性等性能指标，具有良好的经济及环境效益。
