Coal gangue baking-free brick and manufacturing method thereof
The invention discloses a coal gangue baking-free brick which is prepared from the following raw materials in parts by weight: 50-70 parts of coal gangue, 5-10 parts of cement, 5-10 parts of sand, 18-25 parts of a cementing material, 2-5 parts of a foaming agent, 0.5-2 parts of an additive and 20-50 parts of water, wherein the cementing material comprises Portland cement clinker and coal gangue fine powder, and the particle size of the coal gangue fine powder is 0.15-5mm. According to the invention, the use amount of coal gangue in the coal gangue baking-free brick is increased, the occupationarea of the coal gangue is further reduced, the pollution of the coal gangue to the environment and the damage of the coal gangue to organisms are alleviated, the high-quality baking-free brick withcharacteristics of light weight, high strength, freezing resistance and high temperature resistance is prepared through reasonable design of the formula and the synergistic effect of the raw materials, and the coal gangue baking-free brick has good economic and social benefits.
本发明公开了一种煤矸石免烧砖，包括以下重量份的原料：煤矸石50~70份，水泥5~10份，砂5~10份，胶结料18~25份，发泡剂2~5份，添加剂0.5~2份和水20~50份；其中，所述胶结料包括硅酸盐水泥熟料和煤矸石细粉，所述煤矸石细粉的粒径为0.15~5mm。本发明提高了煤矸石免烧砖中煤矸石的用量，不仅进一步减少了煤矸石的占地面积，缓解了煤矸石对环境的污染和生物的伤害，还通过对配方的合理设计，原料之间相互协同作用，制备出具有质量轻、强度高、抗冻耐高温的高质量免烧砖，具有良好的经济和社会效益。
