| Abstract: | phosphogypsum is a byproduct produced in the production of phosphoric acid and phosphate fertilizer. One ton of phosphogypsum will produce about 4.8 tons of phosphogypsum. The utilization of phosphogypsum resource not only makes rational use of calcium sulfate resource, but also solves the harm caused by free storage of phosphogypsum. This paper introduces the development of phosphogypsum utilization, including the pretreatment and utilization of phosphogypsum, and emphatically introduces the application of phosphogypsum in building materials. |
