Abstract

The invention discloses a sintered fly ash-expanded perlite water-permeable brick and a preparation method thereof. With high-carbon content fly ash, clay, silica powder, bauxite and expanded perlite as raw materials, the sintered fly ash-expanded perlite water-permeable brick is sintered by the following formula: 30 to 50 percent of the high-carbon content fly ash, 50 to 70 percent of the clay, 0 to 5 percent of the silica powder, 0 to 5 percent of the bauxite, and 50 to 120 percent of the expanded perlite; in the formula, the high-carbon content fly ash, the clay, the silica powder and the bauxite are in percentage by mass, and the total mass of the four types of raw materials is 100 percent; and the expanded perlite is in percentage by volume, i.e. the percentage by volume of the expanded perlite in the volume of a mixture of the high-carbon content fly ash, the clay, the silica powder and the bauxite. The water-permeable brick prepared by the invention has the advantages of good water permeability, high strength, environment-friendliness and energy saving, and is applicable to water-permeable paved structures and pavements of sidewalks, communities, squares, parking lots and the like.

Description

technical field [0001] The invention belongs to the field of permeable paving materials, in particular to a sintered fly ash expanded perlite permeable brick and a preparation method thereof. The sintered fly ash expanded perlite permeable brick prepared by the method is suitable for pavement structures and road surfaces that require water permeability, such as sidewalks, squares, and residential roads. Background technique [0002] The permeable pavement structure and pavement have the functions of alleviating urban waterlogging and regulating urban water resources and ecosystems, and are an important part of the construction of "sponge city". As a component unit of a permeable pavement structure, permeable bricks have their water permeability derived from the pores contained in the bricks and the permeable channels formed by them. The higher the porosity of the permeable brick, the more abundant the permeable channels and the better the permeable performance. [0003] In...
