Lightweight high-strength water permeable brick with photocatalysis effect

Abstract

The invention discloses a lightweight high-strength water permeable brick with a photocatalysis effect. The lightweight high-strength water permeable brick comprises a reverse osmosis layer, a water permeable layer and a photocatalysis layer in sequential distribution from bottom to top. The photocatalysis layer is coated with a cement-based material with a photocatalysis property; the water permeable layer is formed by pouring of ceramsite-doped regenerated lightweight aggregate concrete; the reverse osmosis layer is also formed by pouring of ceramsite-doped regenerated lightweight aggregate concrete. The lightweight high-strength water permeable brick structurally comprises three layers, namely the photocatalysis layer, the water permeable layer and the reverse osmosis layer, from top to bottom, and each of the three layers has certain porosity. The photocatalysis layer is capable of effectively treating motor vehicle exhaust; the water permeable layer is effective in water drainage; the reverse osmosis layer is effective in reduction of influences of the heat island effect on the environment.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a light high-strength permeable brick with photocatalytic effect. Background technique [0002] With the development of my country's construction industry and the popularization of automobiles, the massive construction of concrete pavements in cities will easily cause urban waterlogging in cities with poor drainage infrastructure during the rainy season, which has a serious impact on the lives of urban residents. The heat island effect is easy to occur when the temperature is high in summer. On the other hand, the color of concrete or asphalt pavement is monotonous, which is easy to cause visual fatigue to drivers or pedestrians. Moreover, with the continuous increase of automobiles and other motor vehicles, more and more harmful exhaust gases are produced. Motor vehicle exhaust is the main cause of urban smog. However, traditional concrete is powerless against harmful gas...

On the other hand, the color of concrete or asphalt pavement is monotonous, which is easy to cause visual fatigue for drivers or pedestrians

Moreover, with the continuous increase of automobiles and other motor vehicles, more and more harmful exhaust gases are produced. Motor vehicle exhaust is the main cause of urban smog. However, traditional concrete is powerless against harmful gases.

[0003] Although permeable concrete, permeable asphalt concrete and permeable bricks currently on the market can discharge water, the effect is not obvious, and the harmful exhaust gas produced by automobiles cannot be effectively treated, and construction waste and other harmful to the environment cannot be effectively used. At the same time, the existing permeable bricks have a high density, which makes transportation troublesome and consumes a lot of energy
