Color-changing baking-free water-permeable brick by using solid waste and preparation method

Abstract

The invention discloses a color-changing baking-free water-permeable brick by using a solid waste and a preparation method, solves the problem of the large energy consumption of the water-permeable brick product in the prior art, and has the beneficial effects that the existing solid waste can be fully utilized, the energy is saved, and the social environment is protected. The scheme is as follows: the color-changing baking-free water-permeable brick by using the solid waste comprises a surface layer and a base layer, wherein the surface layer and the base layer are combined together, the surface layer comprises a ceramic waste, a water glass solution, color-changing glass particles and water, the base layer comprises a red mud, a ferrous aluminate cement, an aggregate, a water reducing agent and an early strength agent, and the ceramic waste, the color-changing glass particles, the red mud, the ferrous aluminate cement and the aggregate are all derived from the solid waste.

Description

technical field [0001] The invention relates to the field of utilization of industrial waste slag resources, in particular to a color-changing burn-free permeable brick utilizing solid waste and a preparation method thereof. Background technique [0002] Red mud is an industrial solid waste discharged from the aluminum industry after refining alumina from bauxite. Generally, for every ton of alumina produced, one ton of red mud is incidentally produced. According to incomplete statistics, the annual discharge of red mud in my country is as high as tens of millions of tons, and the cumulative storage of more than tens of millions of tons has been accumulated. The utilization rate of red mud is low, and a large amount of red mud cannot be fully and effectively utilized, and a large amount of red mud is accumulated on flat land and hillsides. , occupying a large amount of land and causing serious harm to the environment. Therefore, it is imminent to reduce the output and harm ...

Problems solved by technology

[0004] The pursuit of the quality of permeable bricks is still the direction pursued by researchers who use permeable building materials. The inventor found that there are permeable bricks designed in the prior art, but the main material of permeable bricks is cement, and the energy consumption of cement production is relatively large. , the production cost is high, and energy-saving development cannot be realized; in addition, the strength and wear resistance of the permeable bricks manufactured in the prior art need to be further improved
