Abstract

An water-permeable concrete brick suitable for high-load pavement features that the polymer and high-hydroscopicity and-strength shale ceramsite are used to modify the sand-free porous cement concrete for improving elasticity, adhesive to aggregate, mechanical performance and durability.

Description

technical field [0001] The invention belongs to a water-permeable road brick. Background technique [0002] Porous cement concrete pavement has a series of advantages: good drainage, anti-skid and noise reduction performance, and has been applied in many occasions. However, its further application is limited due to the following two shortcomings: [0003] (1) The mechanical properties of porous cement concrete are poor, especially the elasticity of cement paste is poor, and it cannot withstand the dynamic stress of traffic, so its durability is not good, and it has not been applied on automobile roads. [0004] (2) Porous cement concrete has a very narrow application range of moisture content in its raw material ratio, which makes it difficult to control the moisture content, resulting in a higher failure rate during on-site pouring of porous cement concrete permeable pavement or production of porous cement concrete pavement bricks. It also limits the expanded application ...
