赤泥是氧化铝厂利用铝土矿制取氧化铝的过程中排放的一种工业固体废弃物,其组成和性质因铝土矿品位、生产工艺的不同而不同。本研究利用氧化铝厂的赤泥、粉煤灰等工业固体废弃物制备新型墙体材料——免烧砖。赤泥免烧砖原 Red mud is an industrial solid waste discharged by the alumina plant in the process of preparing alumina from bauxite. Its composition and properties are different due to the bauxite grade and the production process. In this study, the use of alumina plant red mud, fly ash and other industrial solid waste prepared a new type of wall material - Burn-free brick. Red mud unburned brick original
