Long-acting antibacterial sand-based water permeable brick and manufacture method thereof

Abstract

The invention discloses a long-acting antibacterial sand-based water permeable brick. Salix leaves and elm barks are charred and ground at room temperature, and carboxymethyl chitosan is adsorbed to the porous surface, so that the adsorbability and long-acting sterilization of a product can be improved; modified sugar filter mud is used as a pore-forming agent, desert sands are washed and dried, and are matched with silicon carbide ceramic clinker, zeolite and other coarse aggregate to remarkably improve the strength and fracture resistance of the product on the premise that the water permeability of a brick body is not influenced. The sand-based water permeable brick prepared by utilizing the method is simple in process and low in production cost, has the advantages of high porosity, excellent water and air permeability and excellent water retaining effect, can be used for cooling, reducing noise and regulating climate, and has multiple functions of eliminating urban heat island effect, improving air quality, maintaining surface water circulation and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a long-acting antibacterial sand-based permeable brick and a manufacturing method thereof. Background technique [0002] In recent years, sand-based permeable bricks have become a hot spot of attention. This sand-based permeable brick is made of sand in the desert. It has good water permeability and non-slip performance. It is not easy to be blocked by dust like ordinary permeable bricks, but the cost is too high. Promoting sand-based permeable bricks is an effective way to realize desert sand resources. On the one hand, in the case of increasingly scarce ore resources, desert sand can be used as a cheap building material. Turning waste into treasure is beneficial. However, there are few studies on sand-based permeable bricks at present. The traditional sand-based permeable bricks have backward production technology, high cost, single function, compressive strength an...

[0002] In recent years, sand-based permeable bricks have become a hot spot of attention. This sand-based permeable brick is made of sand in the desert. It has good water permeability and non-slip performance. It is not easy to be blocked by dust like ordinary permeable bricks, but the cost is too high. Promoting sand-based permeable bricks is an effective way to realize desert sand resources. On the one hand, in the case of increasingly scarce ore resources, desert sand can be used as a cheap building material. Turning waste into treasure is beneficial

However, there are few studies on sand-based permeable bricks at present. The traditional sand-based permeable bricks have backward production technology, high cost, single function, compressive strength and water permeability can not meet the industry standards of permeable bricks at the same time.
