Sintering-free water-permeable brick resistant to abrasion and high in strength
The invention discloses a sintering-free water-permeable brick resistant to abrasion and high in strength. The brick is prepared from, by weight, 50-53 parts of desert sand, 4-5 parts of thermoplastic phenolic resin, 0.6-0.7 part of urotropin, 0.2-0.22 part of calcium stearate, an appropriate volume of water, 42-45 parts of Portland cement with mark number of 42.5, 5-6 parts of coal ash, 2-3 parts of water glass, 1.5-2 parts of polyvinyl acetate emulsion, 9-10 parts of bauxite, 80-85 parts of steelmaking slag, 30-34 parts of silica fume, 1.5-2 parts of sodium lignin sulfonate and 29-32 parts of stone ballast. By adding bauxite to the surface layer material, adding steelmaking slag, stone ballast and other components to the bottom layer material, using all the materials in cooperation and fully using the characteristics of all types of filler, the water-permeable brick which is green, environmentally friendly and low in cost is prepared, and the brick has high strength and abrasion resistance and can be widely applied to places such as pedestrian pavements, parks and squares.
