Cementing powder special for full-tailing cemented filling and preparation method thereof
The invention belongs to the field of cementing materials for mine filling, and relates to cementing powder special for full-tailing cemented filling and a preparation method of the special cementing powder. The cementing powder consists of a cementing powder main material and a modifier, wherein the ratio of the cementing powder main material to the modifier is (90-100):(0-10). The cementing powder main material comprises the following components in percentage by mass: 55%-80% of water-quenched slag, 5%-20% of carbide slag, 10%-30% of fluorgypsum, 5%-10% of 42.5 cement clinker and 5%-20% of salty mud. The material is used for cementing full tailings containing more fine particles, so that a full tailings filling body has higher strength, and the material has the advantages of full utilization of industrial wastes, low cost and reliable effect.
本发明属于矿山充填胶凝材料领域,涉及一种全尾砂胶结充填专用胶固粉及其制备方法。由胶固粉主料和改性剂组成,胶固粉主料:改性剂=90‑100:0‑10。所述的胶固粉主料成分及质量占比为:水淬渣:55%‑80%、电石渣:5%‑20%、氟石膏:10%‑30%、42.5水泥熟料:5%‑10%、盐泥5%‑20%。将该材料用于胶结含细颗粒较多的全尾砂,可使全尾砂充填体有较高的强度,而且该材料具有充分利用工业废弃物,成本低廉,效果可靠的优点。
