Composite water permeable brick

Abstract

A composite water permeable brick comprises water permeable surface and base closely combined together with aggregate and adhesive coating the aggregate, with the adhesive of the said water permeable surface including at least hydrophilicity adhesive. It can keep fine water permeability, with the brick surface fine and close and reduced in cost.

Description

Technical field:

[0001] The invention relates to a water-permeable building material, in particular to a water-permeable brick. Background technique:

[0002] At present, the lack of energy and water resources in the world, the expansion of desertification area and the frequent occurrence of sandstorms have made the living environment of human beings worse and worse. At present, the places where urban residents live are mainly surrounded by urban squares, commercial streets, sidewalks, community activity places, parking lots, etc., which are paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt.
