Problems solved by technology

[0004] As a new building decoration material, permeable bricks are currently the focus of research due to their excellent environmental performance, excellent use performance and good decorative effects. However, due to the popular research on permeable bricks in recent years, Due to the selection of raw materials, the variety of preparation methods and the failure to pay attention to the above-mentioned factors affecting the water permeability of permeable bricks, the quality of the prepared permeable bricks is uneven, and the water permeability of some permeable bricks is extremely low, which seriously affects the permeable bricks. At the same time, it is difficult for consumers to obtain high-quality permeable bricks. Therefore, scientific and reasonable optimization of raw materials for traditional permeable bricks is carried out, and scientific and reasonable improvements are made to the preparation methods to improve the quality of current permeable bricks. The field of building materials is of great significance

Abstract

The invention relates to the technical field of a building material, in particular to a novel pervious brick and a preparation method. The novel pervious brick is prepared from the following raw materials in parts by weight: 100 to 140 parts of industrial waste slag, 40 to 60 parts of urban waste slag, 25 to 35 parts of desulfurization gypsum, 18 to 22 parts of modified bentonite, 35 to 45 parts of surfactants and 20 to 30 parts of bonding agents. The novel pervious brick has the advantages that the pores of a brick body is effectively improved; the goal of improving the water permeable rate is achieved; the water permeable effect is obvious; the water permeable coefficient at 15 DEG C reaches 1.06*10<-2> / s or higher.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a permeable brick and a preparation method thereof. Background technique [0002] At present, the lack of energy and water resources in the world, and the expansion of desertification area and frequent occurrence of sandstorms have made the living environment of human beings increasingly harsh. At present, the places where urban residents live are mainly made of impermeable materials such as granite, marble, glazed tiles, cement and asphalt. Surrounded by the ground of city squares, commercial streets, sidewalks, community activities, parking lots, etc. paved with materials, the hardened ground is very harmful to the urban environment. Landlogged water makes people's travel very inconvenient; precious water resources finally flow away with the drainage pipes, which increases the burden on urban drainage facilities; a large amount of rainwater loss makes it difficult fo...
