Coal gangue ceramsite and preparation method thereof
The invention discloses coal gangue ceramsite and a preparation method thereof, and relates to a building material and a preparation method thereof, wherein the coal gangue ceramsite comprises the following raw materials by weight: 62%-92% of coal gangue, 8%-12% of carbide slag, and 10%-30% of quartz tailings, the coal gangue is uncalcined coal gangue or calcined coal gangue or a mixture of the uncalcined coal gangue and the calcined coal gangue, the carbide slag is solid waste discarded after chemical industry products are prepared from acetylene, and the quartz tailings are solid waste abandoned in a quartz production process. According to the invention, coal gangue, carbide slag and quartz tailings in ceramsite manufacturing raw materials are all solid waste, and the maximum mixing amount of the coal gangue in the raw materials is 92%, so that the problems that the coal gangue pollutes the earth surface and the atmosphere and wastes land are effectively solved, and resource utilization of the waste is effectively achieved; and shale and clay resources are not used as ceramsite raw materials, so that the ecological environment is effectively protected; and the ceramsite preparedby the method is simple in formula, low in stacking density and low in raw material cost.
本发明公开了一种煤矸石陶粒及其制备方法，涉及建筑材料及其制备方法，煤矸石陶粒包含以下重量份原料：煤矸石62％‑92％，电石渣8％‑12％，石英尾矿10％‑30％。煤矸石为未煅烧煤矸石或者煅烧煤矸石或者为未煅烧煤矸石与煅烧煤矸石的混合物。电石渣为乙炔制取化工产品后遗弃的固体废弃物。石英尾矿为石英生产过程中遗弃的固体废弃物。陶粒制作原料中的煤矸石、电石渣、石英尾矿全部为固体废弃物，原料中煤矸石掺量最高为92％，有效解决了煤矸石对地表和大气污染以及浪费土地的问题，有效地实现废弃物资源化利用。陶粒原料不使用页岩和粘土资源，有效的保护生态环境。利用该方法制备陶粒，配方简单，堆积密度低，原料成本低廉。
