Tailing filling cementing material for improving compressive strength of micro-fine particle paste tailing consolidated body and application of tailing filling cementing material
The invention relates to the field of tailing filling, and particularly discloses a tailing filling cementing material for improving the compressive strength of a micro-fine particle paste tailing consolidation body. The tailing filling cementing material is prepared from, by weight, 50-70 parts of blast furnace slag, 15-25 parts of cement, 15-25 parts of gypsum and 17-22 parts of promoting components, the promoting components comprise an accelerant, a compensating agent and a connecting agent, and the weight ratio of the accelerant to the compensating agent to the connecting agent is (3-6): (2-4): 12. The tailing filling cementing material provided by the invention can be used for filling fine-fraction tailings, and has the advantage of promoting the development of early strength.
本申请涉及尾矿充填的领域，具体公开了一种提高微细粒膏体尾矿固结体抗压强度的尾矿充填胶凝材料。该尾矿充填胶凝材料包括以下重量份的原料：高炉矿渣50～70份、水泥15～25份、石膏15～25份、促进组分17～22份，所述促进组分包括促进剂、补偿剂和连接剂，所述促进剂、补偿剂和连接剂三者重量之比为3～6:2～4:12。本申请的尾矿充填胶凝材料可用于细粒级尾矿填充，其具有促进早期强度发展的优点。
