Abstract

The invention relates to the technical field of building materials, in particular to a water permeable brick prepared from ceramsite. The water permeable brick prepared from the ceramsite is integrally formed and is prepared from the following raw materials in parts by weight: 40 to 60 parts of ceramsite, 15 to 25 parts of gravel, 10 to 15 parts of silica sand, 10 to 25 parts of Portland cement and 0.15 to 0.25 part of a water reducing agent; the ceramsite is prepared from casting fly ash, Portland cement, a balling agent, a water reducing agent and a waterproof agent. According to the water permeable brick, the ceramsite serves as the raw material, so that the water permeable brick has good water permeability and water retention rate, the gravel, the water reducing agent, the waterproof agent and the like are used in cooperation, the strength of the water permeable brick is guaranteed, the compressive strength of the water permeable brick is 30-35 MPa, the compressive strength requirement under the conventional application environment is met, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a permeable brick made of ceramsite. Background technique [0002] In order to avoid urban waterlogging, permeable bricks are widely used in urban road renovation. Ordinary permeable bricks on the market are made by pressing crushed stones with concrete. In addition, there are many materials for permeable bricks, which can be divided into: polymer fiber concrete permeable bricks, colored stone composite concrete permeable bricks, colored stone epoxy whole body permeable bricks and concrete permeable bricks. There are more or less partial defects in the above permeable bricks. Colored stone epoxy permeable bricks need to be glued with imported modified epoxy resin, the production cost is relatively high, and it cannot be mass-produced and popularized. The colored stone composite concrete permeable brick is divided into a surface layer and a base layer. The pressing p...
