Mine filling cementing material
The invention discloses a mine filling cementing material which comprises the following raw materials in percentage by mass: 70%-90% of slag, 0%-15% of fly ash, 5%-20% of gypsum, 1%-5% of clinker, 0%-5% of lime and 0.5%-2% of an excitant. The production process is simple, can be briefly described as 'two times of grinding and one time of mixing', namely slag grinding, auxiliary material grinding and finished product mixing, and is low in production cost, low-carbon and environment-friendly. A relatively low mixing ratio of the cementing material to the tailings can be realized, and the mine filling cost is further reduced.
本发明公开了一种矿山充填胶凝材料，包括包括以下质量分数的原料：矿渣70％‑90％、粉煤灰0％‑15％、石膏5％‑20％、熟料1％‑5％、石灰0％‑5％、激发剂0.5％‑2％，本发明生产工艺简单，可简述为“两磨一混”，既矿渣粉磨、辅料粉磨和成品混合，生产成本低廉，低碳环保；可实现较低的胶凝材料与尾砂混合配比，进一步降低矿山充填成本。
