Corrosion resistant water permeable brick
The present invention relates to a corrosion resistant water permeable brick, and belongs to the technical field of building materials. The corrosion corrosion resistant water permeable brick comprises 20-25wt% of Portland cement, 1.0-1.2wt% of anhydrite powder, 15.0-20.0wt% of slag pellets, 10-12wt % of cenospheres, 1.5-2.1wt% of admixtures, and the balance of quartz sand. Under the premise that the porosity and water permeability coefficient of the corrosion resistant water permeable brick are significantly higher than that of a water permeable brick, the compressive strength of the corrosion resistant water permeable brick is still higher than that of the conventional water permeable brick, the corrosion resistant water permeable brick has good corrosion resistance, and service life is significantly increased.
