Cementing material containing industrial solid waste, mine cemented filling material and preparation method of cementing material and mine cemented filling material
The invention provides a high-strength cementing material containing industrial solid waste and a preparation method of the high-strength cementing material, and provides a cementing material containing industrial solid waste, a mine cemented filling material and preparation methods of the cementing material and the mine cemented filling material. The cementing material containing the industrial solid waste comprises the following components in percentage by mass: 5%-15% of iron tailings, 55%-70% of superfine slag powder, 5%-10% of fly ash, 5%-10% of desulfurized fly ash and 10%-15% of cement clinker. According to the invention, solid wastes such as iron tailings, desulfurized fly ash, slag and fly ash are used as raw materials to prepare the cementing material with strength higher than that of traditional Portland cement, the strength development period is short, the hydration rate is high, the required cost is low, and the application of the cementing material in mine filling is effectively promoted.
针对于本发明提供了一种含工业固废高强度胶凝材料及其制备方法，本发明提供了一种含工业固废的胶凝材料和矿山胶结充填材料及制备方法。所述的含工业固废的胶凝材料包括以下质量百分数的组分：铁尾矿5％～15％，矿渣微粉55％～70％，粉煤灰5％～10％，脱硫灰5％～10％，水泥熟料10％～15％。本发明以铁尾矿、脱硫灰、矿渣和粉煤灰等固废为原料，制备强度高于传统硅酸盐水泥的胶凝材料，且强度发展周期短，水化速率快，所需成本低，有效推进胶凝材料在矿山充填中的应用。
