Fly ash autoclaved environment-friendly brick and preparation method thereof
The invention discloses a fly ash autoclaved environment-friendly brick and a preparation method thereof. Fly ash, calcium carbide slurry and stone chips are proportionally and sequentially blended and then crushed and compounded by a compound crusher to form a mixture with a certain particle size, the mixture is uniformly mixed and stirred by a double-shaft stirrer, a proper amount of water is injected, and then the mixture is subjected to standing to complete blending, the prepared mixture is sent to a brick press, after compression molding, the mixture is put into a still kettle to be cured in high-temperature and high-pressure steam to prepare the fly ash autoclaved environment-friendly brick, the required raw materials are only fly ash, calcium carbide slurry and stone chips which are industrial solid wastes, and sintering and addition of other binders are not needed in the preparation process, so that the cost is reduced, and energy conservation and environmental protection are realized. The fly ash autoclaved environment-friendly brick prepared by the method has the compressive strength of more than 10MPa, can meet the use requirements of daily decorative buildings, and has the advantages of reducing resource waste, reducing environmental pollution, saving production cost and increasing economic benefits.
本发明公开了一种粉煤灰蒸压环保砖及其制备方法，将粉煤灰、电石泥、石屑按配比和顺序进行配料后经复合破碎机破碎复合，形成一定粒径大小的混合料，再经过双轴搅拌机混合搅拌均匀，注入适量水，随后进行静置完成配料，将配好的混合料送至压砖机，压制成型后放入蒸压釜中在高温高压蒸汽中养护制得粉煤灰蒸压环保砖，所需原料仅为粉煤灰、电石泥和石屑，均为工业固体废料，制备过程中不需要烧结和添加其它粘结剂，从而降低了成本，节能环保。本发明制备的粉煤灰蒸压环保砖抗压强度达到了10MPa以上，能够满足日常装饰建筑的使用要求，具有减少资源浪费、降低环境污染、节省生产成本，增加经济效益的优点。
