磷石膏在建材行业的应用研究进展

Research Progress on Application of Phosphogypsumin Building Materials Industry

工业副产磷石膏的大量堆存不仅给企业和环境带来了巨大压力,而且造成了资源浪费。国家各主管部门对磷石膏等工业固废的综合利用出台了相关指导意见。文章介绍了我国磷矿资源的分布及近年磷石膏的产排量及利用情况。分析了磷石膏中杂质对建材的影响,重点讨论了磷石膏在建材原料和制品方面的实验研究和工业应用。最后对磷石膏在建材领域的开发研究进行了展望。

The stockpiling of phosphogypsum not only brings great pressure to enterprises and the environment,but also causes a waste of resources.Relevant guidance has been issued to the comprehensive utilization of industrial solid wastes such as phosphogypsum.The distribution of phosphate ore resources in China and the production,discharge and utilization of phosphogypsum in recent yearswas introduced.The influence of impurities in phosphogypsum on building materials was analyzed,and the experimental research and industrial application of phosphogypsum in building materials and products were mainly discussed.The development of phosphogypsum in the field of building materials was prospected.
