Self-flow type cemented filling material containing molybdenum tailings and preparation method of self-flow type cemented filling material
The invention discloses a self-flow type cemented filling material containing molybdenum tailings and a preparation method of the self-flow type cemented filling material. The filling material comprises a gelling material and aggregate, the mass ratio of the gelling material to the aggregate is 1: 4-1: 7, the aggregate is molybdenum tailings, and the gelling material comprises the following components in percentage by mass: 50-80% of converter steel slag, 20%-30% of desulfurized gypsum; and 0-20% of fly ash. The raw materials are all industrial solid wastes, so that the method has remarkable environmental benefits; according to the invention, cement clinker and granulated blast furnace slag are not used, and a chemical activator is not needed, so that the filling material has good performance; and the material also has the advantages of simple preparation process and low production cost.
本发明公开了一种含钼尾矿的自流型胶结充填料及其制备方法。充填料包括胶凝材料和骨料，所述胶凝材料与骨料的质量比为1:4～1:7，所述骨料为钼尾矿，所述胶凝材料，按质量百分比计，包括：转炉钢渣50％～80％；脱硫石膏20％～30％；粉煤灰0％～20％。本发明原材料全部都是工业固体废弃物，具有显著的环境效益；本发明不使用水泥熟料和粒化高炉矿渣，且无需使用化学激发剂，即可使得充填料具有良好的性能；本发明还具有制备工艺简单，生产成本低的优点。
