The invention discloses a mine filling cementing material based on ardealite, which belongs to the field of industrial solid waste recycling and comprises the following components in percentage by mass: 62-82% of ardealite, 15-35% of water-quenched slag and 3% of carbide slag. When in use, the mine filling cementing material based on the phosphogypsum is mixed with water to prepare slurry, the result of the embodiment shows that the compressive strength meets the filling requirements of general mines, the leached pollutants do not exceed the related environmental standards, the comprehensive utilization rate of the phosphogypsum is effectively increased, and the cost is reduced. The current situation that cement needs to be added for cementing in a traditional cementing material is overcome, the filling cost is effectively reduced, the manufacturing process is simple, and operation feasibility is good.
发明公开了一种基于磷石膏的矿山充填胶凝材料,属于工业固体废物资源化领域,其组成物及质量百分比为磷石膏62~82%、水淬渣15~35%、电石渣3%;本发明基于磷石膏的矿山充填胶凝材料使用时与水混合制得浆料,实施例结果显示其抗压强度符合一般矿山的充填要求,且浸出的污染物未超出相关环境标准,本发明有效提高了磷石膏的综合利用率,克服了传统胶凝材料需添加水泥胶结的现状,有效降低了充填成本,制作工艺简单,操作可行性好。
