Problems solved by technology

However, in rainy and snowy weather, when this kind of brick encounters muddy water, the mud in the muddy water will block the gap between the sand grains and the stone grains, reduce the water permeability and affect road traffic.
[0003] In recent years, although my country has made great progress in environmental governance, there is still a big gap compared with developed countries such as Northern Europe, Australia and New Zealand. The sludge and sewage will completely lose the permeable function of the permeable channels of the above permeable bricks in less than one year.
[0004] It can be seen that the pollution resistance and water permeability problems of the above-mentioned permeable bricks are still the bottleneck hindering the popularization and application of permeable bricks; moreover, with natural sand and gravel as the main material, a large amount of natural gravel needs to be mined, which is not conducive to the protection of the ecological environment

Abstract

The invention discloses ecological slag permeable bricks and a preparation method thereof. Each ecological slag permeable brick comprises a basic strength permeable layer and a perceptive permeable layer which is formed by graded distribution and vibrating extrusion molding and is adhered to the upper surface of the basic strength permeable layer. The preparation method for the ecological slag permeable bricks comprises the following steps of: uniformly stirring 70 to 80 parts of ecological slag, 16 to 20 parts of cement, 2 to 5 parts of siliceous dust, 1 to 3 parts of melamine and 5.6 to 8.0 parts of water to prepare the basic strength permeable layer; and uniformly stirring 17 to 22 parts of cement, 65 to 75 parts of quartz sand, 3 to 4 parts of pigment, 2 to 7 parts of waterborne resinand 3.4 to 6.6 parts of water to prepare the perceptive permeable layer. The ecological slag permeable bricks and the preparation method thereof can overcome the defects of poor soiling resistance, poor water permeability and the like in the prior art, and have the advantages of high pollutant resistance, high water permeability, low cost, high environmental friendliness, and attractive appearance.

Description

Technical field [0001] The invention relates to building materials, in particular to an ecological slag permeable brick and a preparation method thereof. Background technique [0002] At present, in our country, permeable bricks can be made with natural sand and gravel as the main resource; this permeable brick mainly realizes the function of water permeation through the gap between sand and stone particles. However, in rainy and snowy weather, when this kind of brick encounters muddy water, the mud in the muddy water will block the gap between sand and stone particles, reduce water permeability and affect road traffic. [0003] In recent years, although my country has made great progress in environmental governance, there is still a big gap compared with developed countries such as Northern Europe, Australia and New Zealand. The dust content of the air is still relatively large, and there are also sandstorms, after rain and snow. The sludge and sewage will cause the permeable chan...
