Mine filling cementing material and preparation method thereof
The invention discloses a mine filling cementing material and a preparation method thereof, and relates to the technical field of mine filling material preparation, the mine filling cementing material comprises the following raw materials by mass: 2-6% of cement clinker, 8-14% of anhydrite, 3-4% of pellet desulfurized fly ash, 76-85% of blast furnace granulated slag, and 1-2% of an activator; the raw materials of the cement clinker, the anhydrite, the pellet desulfurization ash, the blast furnace water slag and the exciting agent are dried and then ground, the raw materials are weighed according to the mass ratio, then the raw materials are fully mixed, and the mine filling cementing material is obtained after the raw materials are mixed to be uniform. The anhydrite is prepared by modifying ardealite with calcium oxide, calcium sulfate and isocyanate and then calcining the modified ardealite with sodium silicate at 500-550 DEG C. The mine filling cementing material provided by the invention is low in cost, effectively improves the cementing performance of a product, obviously enhances the compressive strength, effectively reduces the hydration heat of the product, and is suitable for industrial production.
本申请公开了一种矿山充填胶凝材料及其制备方法，涉及矿山充填材料制备技术领域，其按质量百分比包括以下原料：水泥熟料2‑6%、硬石膏8‑14%、球团脱硫灰3‑4%、高炉水渣76‑85%、激发剂1‑2%；将原料水泥熟料、硬石膏、球团脱硫灰、高炉水渣、激发剂烘干后进行研磨，按质量比称取原料，随后进行充分混合，混合均匀后即得到矿山充填胶凝材料。所述硬石膏由磷石膏经氧化钙、硫酸钙、异氰酸酯改性后，配合硅酸钠在500‑550℃下煅烧而成。本申请提供的矿山充填胶凝材料不仅成本较低，而且有效提高了产品的胶结性能，抗压强度明显增强，还有效降低了产品的水化热，适于工业化生产。
