Sintering-free water-permeable brick resistant to abrasion and high in strength

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a non-sintering permeable floor tile with high wear resistance. Background technique [0002] With the intensification of urbanization, the urban surface is gradually being covered by buildings and various concrete and other water-repelling materials. The proportion of impermeable areas is increasing significantly, and the coverage rate in some areas has exceeded 80%. As the drainage capacity of cities is getting worse and worse, when many cities encounter heavy rains, the rainwater on the roads cannot seep quickly, which can easily cause urban waterlogging. Therefore, in order to solve the problem of urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance, a new green and environmentally friendly building material product-permeable bricks emerged as the times require and have developed rapidly.

Problems solved by technology

Since sand-based permeable bricks have only been available for a few years, large-scale use has not yet been formed, and the benefits generated by them have not been studied in depth.
