Anti-fouling and water-permeable brick with natural stone imitating effect and preparation method of anti-fouling and water-permeable brick

Abstract

The invention provides an anti-fouling and water-permeable brick with a natural stone imitating effect and a preparation method of the anti-fouling and water-permeable brick. The anti-fouling and water-permeable brick comprises an anti-fouling and water-permeable surface layer and a water-permeable base layer, wherein the anti-fouling and water-permeable surface layer is prepared from raw materials in parts by mass as follows: 10-15 parts of cement, 0.5-2 parts of an aqueous adhesive, 65-75 parts of modified fine aggregate, 2-4.5 parts of water, 1.5-2 parts of a water-permeable agent and 3-8 parts of pigment; the water-permeable base layer is prepared from raw materials in parts by mass as follows: 15-25 parts of fly ash, 5-10 parts of cement, 10-20 parts of carbide slag, 5-15 parts of slag, 15-20 parts of construction waste, 2-4 parts of the water-permeable agent and 3-8 parts of water. A mass ratio of the anti-fouling and water-permeable surface layer to the water-permeable base layer is 1:(7.5-8.5), and the modified fine aggregate is prepared from one or more fine aggregate of granite debris, marble flakes, quartz sand and silica sand through modification. The anti-fouling and water-permeable brick has the advantages of being high in anti-fouling level, resistant to wear, good in water permeability, high in strength, low in cost and smooth in surface, achieving the attractive natural stone imitating effect and the like.

Description

technical field [0001] The invention relates to a pollution-resistant permeable brick imitating natural stone and a preparation method thereof, belonging to the field of building materials. Background technique [0002] As an important part of the sponge city construction system, pavement permeable bricks play a huge role. In the tide of sponge city construction, its market prospect is extremely broad. Permeable brick has the following advantages: it has good water permeability and air permeability, which can quickly infiltrate rainwater into the ground, replenish soil water and groundwater, maintain soil moisture, and improve the living conditions of urban ground plants and soil microorganisms; it can absorb water and heat, and regulate the ground surface The temperature and humidity of the local space have a great effect on regulating the urban microclimate and alleviating the urban heat island effect; it can reduce the pressure of urban drainage and flood control, and ha...
