Abstract

The invention relates to a red mud permeable brick and a method for preparing the same, and belongs to the field of technologies for recycling red mud. The red mud permeable brick and the method have the advantages that red mud can be recycled, accordingly, the problem of red mud pollution can be fundamentally solved, and permeable materials in urgent need can be provided for constructing sponge cities; the red mud permeable brick is high in permeable rate and compressive and breaking strength and excellent in freezing-thawing resistance, energy can be saved, environmental pollution due to the red mud can be completely eradicated, the red mud can be sufficiently and effectively utilized, and accordingly the economical, durable, healthful, environment-friendly and colorful novel permeable brick can be provided for society.

Description

technical field [0001] The invention relates to a red mud permeable brick and a preparation method thereof, belonging to the technical field of red mud recycling. Background technique [0002] Red mud is the polluting waste residue discharged when the aluminum industry extracts alumina. Generally, for every ton of alumina produced, 1.0 to 2.0 tons of red mud are incidentally produced. As the world's fourth largest producer of alumina, China discharges millions of tons of red mud every year. A large amount of red mud cannot be fully and effectively utilized, so it can only rely on large-scale storage yards, which takes up a lot of land and causes serious pollution to the environment. The red mud produced in the world is about 70 million tons every year, and the red mud produced in my country is more than 30 million tons every year. The production of a large amount of red mud has caused direct and indirect impacts on human production and life in many ways, so how to fully an...
