Multi-fiber toughened non-sintered composite permeable floor brick

Abstract

The invention discloses a multi-fiber toughened non-sintered composite permeable floor brick. The multi-fiber toughened non-sintered composite permeable floor 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 amount of water, 42-45 parts of portland cement with the grade of 42.5, 5-6 parts of fly ash, 0.5-0.6 part of polycarboxylate powder, 1.5-2 parts of polycarboxylate, 3-4 parts of water glass, 6-7 parts of palm fiber, 2-3 parts of sepiolite fibers, 8-9 parts of polypropylene fibers, 70-75 parts of thermal power plant coal slag and 60-63 parts of small titanium stones. According to the multi-fiber toughened non-sintered composite permeable floor brick, the palm fiber is added in a surface layer material, the ingredients such as the sepiolite fibers and the polypropylene fibers are added in a bottom layer material, the toughness and strength of the brick are further improved through the combined action of multiple kinds of the fibers, therefore, the brick is not prone to be broken and durable in use, the urban drainage problem is effectively solved, and a contribution is supplied to construction of a sponge city road surface.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a multi-fiber toughened non-sintering composite permeable floor tile. 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.
