Red mud sand foundation water permeable brick and making method thereof

Abstract

The invention discloses a red mud sand foundation water permeable brick. Carbonization treatment is conducted on lemon peels, livestock and poultry manure and pine needles, room temperature grinding is conducted, nano-titanium dioxide is adsorbed to the pore surfaces, and the adsorptivity and the self-cleaning property of a product are improved; modified sugar filter mud serves as a pore-forming agent, desert sand is washed through water, dried and then combined with coarse aggregates such as bentonite, red mud and copper mill tailings, and the strength and fracture resistance of the product are obviously improved on the condition that the water permeability of the brick is not affected. The sand foundation water permeable brick prepared through the making method has the advantages of being high in raw material utilization ratio, simple in production technology, low in cost and capable of absorbing automobile exhaust and purifying pollutants in water through photocatalysis.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a red mud 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 and water permeabili...
