The invention discloses an environment-friendly brick with good strength. The environment-friendly brick comprises the following raw materials in parts by weight: 60-80 parts of coal gangue, 15-25 parts of crushed powder of building solid waste, 6-10 parts of composite Portland cement No.325, 1-3 parts of an admixture, 2-4 parts of a reinforcing agent and 1-3 parts of water. The invention furtherprovides a preparation method of the environment-friendly brick with good strength. In the environment-friendly brick disclosed by the invention, coal gangue can be used as aggregate, but has the characteristic of easy alkali return, and brick slag powder doped into the crushed powder of the building solid waste can improve product strength while inhibiting alkali return. And after integrally stirring the above ingredients for 2 minutes, a liquid additive accounting for 0.02% of the total weight is added, stirring is conducted again for 1 minute, and then pressing can be conducted. A molded product has no obvious cracks on the surface and is compact in structure, and the appearance of the product meets a production standard.
本申请公开了一种强度好的环保砖，其原料按重量份包括：煤矸石60‑80份、建筑固废破碎粉状物15‑25份、325#复合硅酸盐水泥6‑10份、外掺剂1‑3份、补强剂2‑4份、水1‑3份。本发明还提出的一种强度好的环保砖的制备方法。本发明的环保砖中，煤矸石本身可作为骨料使用，但其特点易返碱，掺入建筑固废破碎粉状物内的砖渣粉在抑制返碱的同时可增加产品强度。配料整体搅拌2分钟后，加入总重量2‰的液态外掺剂再次搅拌1分钟，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。
