[0028] A method for preparing a water-permeable brick includes a surface layer and a bottom layer, the surface layer and the bottom layer are tightly combined into one body; the surface layer and the bottom layer respectively contain aggregate and a binder for bonding the aggregate.
[0029] The aggregates are ceramic waste, hard kaolin and coal gangue. Wherein, the grain size of the aggregate of the surface layer is 10-18 mesh, and the grain size of the aggregate of the bottom layer is 5-10 mesh.
[0030] Ceramic waste with low water absorption has the characteristics of high temperature resistance, hardness and wear resistance. On the one hand, it can improve the strength of the permeable brick and increase its wear resistance; on the other hand, the ceramic waste has very little melting during high-temperature roasting and acts as a skeleton.
[0031] Hard kaolin is a unique mineral in Guizhou, with high development and utilization value and low cost. Hard kaolin has better cohes...
