Influence of calcination and GGBS addition in preparing β-hemihydrate synthetic gypsum from phosphogypsum

Transforming phosphogypsum (PG) to β-hemihydrate PG with cementitious properties at low calcination temperature is an effective method for large-scale utilization of by-product PG. Nevertheless, due to the poor water resistance of PG, its application and recycling rate is limited. This study aims to...
