High-strength coal gangue ceramsite and preparation method thereof
The invention discloses a high-strength coal gangue ceramsite and a preparation method thereof, and relates to a building material and a preparation method thereof. The high-strength coal gangue ceramsite comprises the following raw materials by weight: 90%-97% of coal gangue, 2%-8% of carbide slag, and 0%-10% of papermaking white mud, wherein the coal gangue is uncalcined coal gangue or calcinedcoal 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 papermaking white mud is solid waste abandoned in a papermaking process. According to the invention, coal gangue, carbide slag and papermaking white mud in ceramsite manufacturing raw materials are all solid waste, and the mixing amount of the coal gangue in the raw materials is higher than 90%, 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 can be effectively achieved; and the ceramsite prepared by the method is simple in formula, low in stacking density, high in cylinder compressive strength, simple in formula and low in raw material cost, and the technological process is adopted.
本发明公开了一种高强煤矸石陶粒及其制备方法，涉及建筑材料及其制备方法，所述的高强煤矸石陶粒包含以下重量份原料：煤矸石90％‑97％，电石渣2％‑8％，造纸白泥0％‑10％。所述的煤矸石为未煅烧煤矸石或者煅烧煤矸石或者未煅烧煤矸石与煅烧煤矸石的混合物。所述电石渣为乙炔制取化工产品后遗弃的固体废弃物。所述造纸白泥为造纸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、造纸白泥全部为固体废弃物，原料中煤矸石掺量高于90％，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，能够有效地实现废弃物资源化利用。利用该方法制备陶粒，配方简单，堆积密度低，筒压强度高，配方简单，原料成本低廉，工艺流程。
