Mine filling cementing material for sulfur-containing tailings
The invention discloses a mine filling cementing material for sulfur-containing tailings. The mine filling cementing material is prepared from the following raw materials in parts by weight: 18-22 parts of cement clinker, 13-17 parts of desulfurized gypsum, 4-6 parts of natural gypsum, 48-54 parts of blast furnace slag powder, 4-6 parts of non-ferrous smelting slag, 2-4 parts of fly ash, 1-3 partsof quick lime, 0.6-0.8 parts of calcined alum and 0.2-0.4 parts of sodium sulfate. The cement clinker, the desulfurized gypsum, the natural gypsum, the blast furnace slag powder, the non-ferrous smelting slag, the coal ash, the quick lime and other raw materials are mixed with the calcined alum and the sodium sulfate which serve as excitants, and the mixture is subjected to ball milling to form the high-activity cementing material. The cementing material has a high specific surface area, so that grains are refined, and the strength of a hardened body is high.
本发明公开了一种针对含硫尾砂的矿山充填胶凝材料，由以下重量份原料制成：水泥熟料18‑22、脱硫石膏13‑17、天然石膏4‑6、高炉矿渣粉48‑54、有色冶炼渣4‑6、粉煤灰2‑4、生石灰1‑3、煅烧明矾0.6‑0.8以及硫酸钠0.2‑0.4。本发明采用水泥熟料、脱硫石膏、天然石膏、高炉矿渣粉、有色冶炼渣、粉煤灰、生石灰等原料和作为激发剂的煅烧明矾以及硫酸钠混合球磨，形成高活性胶凝材料，本发明的胶凝材料有着较高的比表面积，进而使得晶粒细化，硬化体的强度高。
