Environment-friendly baking-free brick produced by utilizing granite mine tailings and preparation method of environment-friendly baking-free brick
The invention relates to the technical field of comprehensive utilization of resources and building materials, and particularly provides an environment-friendly baking-free brick produced by utilizing granite mine tailings and a preparation method of the environment-friendly baking-free brick. According to the baking-free brick, tailings generated in the aggregate production process of a granite mine serve as a base body, the tailings mainly comprise stone powder, mud, biotite and other substances, and the baking-free brick is prepared from, by weight, 55%-70% of tailings, 8%-16% of cement, 5%-13% of quick lime, 7%-15% of water glass and 6%-10% of water. The preparation method comprises the following steps: weighing the quick lime and the tailings in proportion, forcibly stirring uniformly, aging for 6 hours, adding the cement, the water glass and the water, fully stirring, performing pressure forming, demolding, and curing for 7-10 hours by using steam at 80-100 DEG C. The baking-free brick produced from the granite mine tailings is free of a sintering process, a large amount of carbon emission is avoided, solid waste of the granite mine tailings is recycled, and multiple purposes are achieved at one stroke.
本发明涉及资源综合利用和建筑用材料技术领域，具体提供的是一种利用花岗岩矿山尾渣生产的环保免烧砖及其制备方法。所述免烧砖以花岗岩矿山生产骨料过程中产生的尾渣为基体，尾渣主要含有石粉、泥浆、黑云母等物质，按如下重量份的原料制得，尾渣55％‑70％、水泥8％‑16％、生石灰5％‑13％、水玻璃7％‑15％、水6％‑10％。其制备方法包括如下步骤，按比例称取生石灰与尾渣强制搅拌均匀后陈化6小时，加入水泥、水玻璃、水经充分搅拌后压力成型，脱模后使用80～100℃蒸汽养护7～10小时。本发明所述的花岗岩矿山尾渣生产的免烧砖无烧结工艺，避免了大量的碳排放，也使花岗岩矿山尾渣固废资源化，一举多得。
