Problems solved by technology

[0003] In order to improve the water permeability, the inside of the permeable concrete aerated brick usually has a porous honeycomb structure, so that the internal structure of the permeable concrete is relatively loose, but at the same time it is easy to cause the hardness of the permeable concrete aerated brick to decrease, so that the compressive strength of the permeable concrete is reduced. , is prone to breakage, therefore, there is still room for improvement

Abstract

The invention relates to the field of building materials. The invention aims to solve the problem of low compressive strength of pervious concrete aerated bricks. The pervious concrete aerated brick comprises the following components in parts by mass: 43-58 parts of fly ash, 22-30 parts of stone powder, 10-14 parts of lime, 58-78 parts of water, 10-14 parts of cement, 3-4 parts of gypsum, 0.08-0.1part of aluminum powder, 0.08-0.1 part of steel fibers and 0.15-0.2 part of fish glue powder. By adding the steel fibers, the hardness of the pervious concrete aerated brick is improved, the compressive strength of the pervious concrete aerated brick is improved, and therefore the pervious concrete aerated brick is not prone to cracking after being formed.

Description

technical field [0001] The invention relates to the field of building materials, more specifically, it relates to a permeable concrete aerated brick. Background technique [0002] Permeable concrete aerated bricks are made of cement, water, and a certain proportion of aggregates. After pouring, static curing, cutting, and high-temperature and high-pressure steam curing, they form a turning block with a certain strength. [0003] In order to improve the water permeability, the inside of the permeable concrete aerated brick usually has a porous honeycomb structure, so that the internal structure of the permeable concrete is relatively loose, but at the same time it is easy to cause the hardness of the permeable concrete aerated brick to decrease, so that the compressive strength of the permeable concrete is reduced. , are prone to breakage, therefore, there is still room for improvement. Contents of the invention [0004] In view of the deficiencies in the prior art, the pu...
