Red mud-lead zinc tailing based geopolymer consolidation material and consolidation body
The invention discloses a red mud-lead zinc tailing based geopolymer consolidation material and a consolidation body. The consolidation material is prepared from the following raw materials in parts by weight: 70 to 80 parts of red mud-lead and zinc tailings mixture, 10 to 20 parts of admixture and 5 to 10 parts of admixture. According to the method, the potential hydration activity of the lead-zinc tailings is excited through the strong alkalinity of the red mud, outflow of alkaline substances in the red mud is reduced, the frost return phenomenon is reduced, and lead-zinc ions in the lead-zinc tailings are solidified and stabilized through hydration products; meanwhile, by adding an admixture and an additive, a hydration reaction is further promoted to generate amorphous N-A-S-H gel, so that a better curing effect on heavy metal lead and zinc is achieved, and finally lead and zinc ions in a cured body leachate formed after curing can meet the surface water class II standard; meanwhile, the solidified body has good mechanical strength and can meet the application requirements in the fields of road engineering, tailing filling and building materials.
本发明公开一种赤泥‑铅锌尾砂基地质聚合物固结材料及固化体。该固结材料，按重量份计，其原料包括：赤泥‑铅锌尾砂混合料70‑80份、掺合料10‑20份、外加剂5‑10份。本发明利用赤泥的强碱性激发铅锌尾砂的潜在水化活性，降低赤泥中碱性物质的流出、减少返霜现象，并利用水化产物固化稳定铅锌尾砂中的铅锌离子；同时通过添加掺合料和外加剂，进一步促进水化反应，生成非晶态N‑A‑S‑H凝胶，从而对重金属铅锌具有更好的固化效果，最终能够使固化后形成的固化体浸出液中铅锌离子满足地表水II类标准；同时固化体具有良好的力学强度，能够满足在道路工程、尾矿充填、建筑材料领域的应用要求。
