ABSTRACT

Phosphogypsum is a by-product emitted from the wet phosphoric acid production process. The massive accumulation of phosphogypsum occupies land resources and pollutes groundwater. Predecessors have made contributions to the utilization of phosphogypsum resources, especially the preparation of pavement base materials using phosphogypsum. It is more conducive to realizing its large-scale utilization. The paper introduces the physical and chemical properties of phosphogypsum, this review summarizes the phosphogypsum modified pavement base materials, Phosphogypsum-cement pavement base material and its hydration mechanism were analyzed. The problems existing in the research on phosphogypsum-based pavement base materials are summarized. Suggestions on resource utilization of phosphogypsum in pavement base materials were also put forward.
