Cementing material and application thereof

The invention belongs to the technical field of mine filling, and concretely relates to a cementing material for a sulfide-containing tailing cemented filling body. The cementing material is preparedfrom, by weight, 0.1-2 parts of water glass, 0.1-2 parts of carbonate, 1-15 parts of active magnesium oxide and 81-99 parts of granulated blast furnace slag powder. A cementing material and sulfide mine tailing cemented filling body has the advantages of no cracks, no reduction of the compressive strength in the late stage, and good economic benefit. 本发明属于矿山充填技术领域，具体涉及种用于含硫化物矿山尾砂胶结充填体的胶凝材料。该胶凝材料由以下重量份数的原料制成：水玻璃0.1-2份、碳酸盐0.1-2份、活性氧化镁1-15份和粒化高炉矿渣粉81-99份，本发明的胶凝材料与硫化物矿山尾砂胶结的充填体不会开裂，后期抗压强度不降低，经济效益好。
