The invention discloses an environment-friendly brick with good firmness. The environment-friendly brick comprises the following raw materials in parts by weight: 70-80 parts of gold tailings, 10-20 parts of a gravel mixture, 6-10 parts of 325# composite Portland cement, 1-3 parts of a liquid admixture and 1-3 parts of water. The invention further provides a preparation method of the environment-friendly brick with good firmness. In the preparation process, the crushed stone mixture can fully crush and grind gold tailing particles in the stirring process, and meanwhile, the firmness and the pressure resistance of the product are also greatly improved. The tailings and the gravels are stirred, then the cement is added for continuous stirring, finally, the liquid admixture is added for stirring, pressing can be achieved, the surface of a formed product has no obvious cracks, the structure is compact, the appearance meets the production standard, and the compression resistance reaches 31.75 MP.
本申请公开了一种牢固性好的环保砖，其原料按重量份包括：黄金尾矿70‑80份、碎石混合物10‑20份、325#复合硅酸盐水泥6‑10份、液态外掺剂1‑3份、水1‑3份。本发明还提出一种牢固性好的环保砖的制备方法。本发明在制备过程中，碎石混合物在搅拌过程中能将黄金尾矿颗粒物充分粉碎研磨，同时也大幅提高产品的牢固性和抗压性。将尾矿与碎石搅拌后加入水泥继续搅拌，最后加入液态外掺剂搅拌，即可压制，成型后产品表面无明显裂纹，结构紧密，外观符合生产标准，抗压性能达到了31.75MP。
