Influence of wet grinded slag on the hydration of phosphogypsum-slag

Phosphogypsum-slag based cement (PSBC) has a great potential in tailings backfill because of low cost and CO 2 emission in comparison with Portland cement. However, slow early hydration was often observed, and this problem was generally solved by adding cement clinker, which could provide alkalinity to hasten the hydration …
