摘要
煤矸石是在煤炭生产过程中产生的一种硅铝质含碳岩石,是目前我国排放量最大的工业固体废弃物之一,占年工业固体废弃物排放量的20%以上。大量堆存的煤矸石处理不当,不仅会对环境造成严重危害,而且是对资源的变相浪费。介绍了煤矸石在水泥领域的应用,阐述了不同品质煤矸石应用到水泥产品领域时所需具备的物化性质。
Coal gangue is one of the largest industrial solid waste of China and accounts for more than 20 % in the industrial solid, which is silicon aluminum carbonaceous mineral generating during the coal producing. Large accumulation of coal gangue can cause environmental problems and a waste of resources. This paper introduces application of coal gangue in the building materials-cement areas and expounds physical and chemical properties of coal gangue with different quality when it applys to the field of cement products.
