Abstract

The invention relates to a preparation method of a ceramsite light water permeable brick road. The method comprises the following steps that S1, firstly, cement, straw particles, ceramsite, overburntlime, a water reducing agent and a water retaining agent are mixed to be uniform, then, mud is added for stirring for 2-6 min, and then standing is performed for 1-3 h; S2, foamed particles are addedinto the product obtained in S1, the mixture is placed under the pressure of 8-12 MPa for pressurizing treatment for 0.5-1.5 h, and then the mixture is taken out for standing under the temperature of90-120 DEG C for 6-8 h; S3, the product obtained in S2 is placed under the temperature of 600-800 DEG C for calcinating for 2-3 h, then, the product is taken out for natural cooling to 80-120 DEG C for maintaining for 12-24 h. The prepared light water permeable brick solves the problems that in the prior art, a light water permeable brick is poor in water permeability and low in mechanical strength, and a foundation is loose due to the fact that water is likely to permeate the material after long-term use.

Description

technical field [0001] The invention relates to the technical field of environmental protection building materials, in particular to a preparation method of ceramsite lightweight permeable bricks. Background technique [0002] Lightweight permeable brick is a new type of environmentally friendly building material. It is often used in squares, parking lots, sidewalks, and roads with small traffic volume and load, such as building and community roads, non-motorized lanes of municipal roads and other pavement projects. It has good water permeability and air permeability, which can quickly infiltrate rainwater into the ground, replenish soil water and groundwater, maintain soil moisture, improve the living conditions of urban ground plants and soil microorganisms, and can adjust the temperature and humidity of local space on the surface, which is very important for regulating urban microclimate. 1. It has a great effect on alleviating the urban heat island effect, and reduces th...
