摘要
赤泥是一种氧化铝生产过程中产生的废渣。大量赤泥堆积如山,占用农田,耗费很多堆场建设和维护管理费用,污染环境。本文对赤泥的化学成分和矿物相进行了叙述;着重综述了化学固化的赤泥在筑坝、建路基、制免烧砖、调节混凝土性能和生产碱矿渣水泥以及烧结赤泥在生产普通硅酸盐水泥、烧结砖、建筑陶粒和建筑陶瓷的研究进展。
Red mud is the major solid waste produced in the process of alumina extraction. The large quantity of red mud causes serious problems such as storing and environmental pollution. This paper narrated chemistry compositions and minerals of red mud, and referred the utilization of chemical solidified red mud in building dam, building roadbed, producing non - fired stakes, modifying for performance of concretes and producing alkali slag cements and the utilization of sintered red mud in producing Portland cements, producing fired stakes, making ceramisite and producing building ceramies.
