Present Situation and Development of Building Material Utilization of Phosphogypsum

摘要


The impurity components of phosphogypsum in China are complex and the accumulation is large. Due to its low utilization rate, the sustainable development of phosphogypsum industry in China is limited. How to effectively digest large amounts of phosphogypsum has become an urgent world problem to be solved. Therefore, according to the application status of phosphogypsum all over the world, in this paper, the characteristics and utilization difficulties of phosphogypsum in China are summarized and analyzed, the application of partial phosphogypsum in building materials is explained, and the future research trend of phosphogypsum utilization is prospected.
