preparation example Construction

[0028] A preparation method of a permeable brick, which comprises a surface layer and a bottom layer, the surface layer and the bottom layer are closely combined; the surface layer and the bottom layer respectively contain aggregate and a binder for bonding the aggregate.

[0029] The aggregate is ceramic waste, hard kaolin and coal gangue. Wherein, the particle size of the aggregate of the surface layer is 10-18 mesh, and the particle size of the aggregate of the bottom layer is 5-10 mesh.

[0030] Ceramic waste with low water absorption has the characteristics of high temperature resistance, hardness and wear resistance. On the one hand, it can improve the strength of permeable bricks and increase its wear resistance;

[0031] Hard kaolin is a unique local mineral in Guizhou, with great development and utilization value and low cost. Hard kaolin has good cohesiveness, good drying shrinkage, good sintering shrinkage and high dry strength, which is conducive to improving the ...

Abstract

The invention discloses a method for producing water-permeable brick. The water-permeable brick comprises a surface layer and a bottom layer, and the surface layer and the bottom layer are closely combined to form one body; the surface layer and the bottom layer respectively comprise aggregates and a binder for bonding the aggregates; and the aggregates are ceramic wastes, hard kaolin and coal gangue. The binder comprises, by weight, 20-30 parts of boron mud, 10-15 parts of lithium feldspar and 8-15 parts of modified diatomaceous earth. The ceramic wastes, hard kaolin and coal gangue are adopted as aggregates, so the use amount of the ceramic wastes is greatly reduced, the current situation of shortage of raw materials is overcome, and industrialized mass production can be easily achieved.Optimized composition design and a reasonable component ratio in the invention facilitate the formation of the microstructure of a compact green brick with a suitable porosity, and effectively improve the compressive strength and the water permeability of the finished water-permeable brick.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of a permeable brick. Background technique [0002] At present, cement, asphalt, marble and other non-permeable materials are mostly used in urban construction to pave the ground. These hardened pavements make it difficult to exchange heat and moisture between the ground surface and the air, and the ability to naturally adjust the temperature and humidity of the urban ground is very poor, and the surface absorbs heat. Difficulties, resulting in a large amount of waste heat in the urban space, and a large amount of reflection on the ground to radiate solar heat, which leads to the phenomenon that the nighttime temperature in the city is higher than that in the suburbs. Moreover, in rainy days, the hardened pavement will prevent rainwater from infiltrating directly into the ground, causing water to accumulate everywhere, affecting the comfort and safety of the...
