Abstract

The invention provides a water permeable brick and a preparation method thereof. The water permeable brick is prepared from the following raw materials in parts by weight: 60-80 parts of blast furnace slag, 5-15 parts of polished slag, 10-20 parts of coal gangue, 15-25 parts of redware ore soil, 8-15 parts of a flux, 0.8-1.2 parts of an adhesive. The preparation method comprises the following steps of (1) material preparing; (2) crushing; (3) ball milling and wet mixing; (4) drying; (5) molding; and (6) burning. According to the preparation method, the water permeable brick which is prepared by adopting the blast furnace slag and the polished slag as main raw materials and adding the coal gangue and the redware ore soil has a relatively good water permeability, and the tensile structure and bending strength of the water permeable brick can be further improved.
