Effect of soluble phosphate, fluoride, and pH in Brazilian phosphogypsum used as setting retarder on Portland cement hydration

Effect of soluble phosphate, fluoride, and pH in Brazilian phosphogypsum used as setting retarder on Portland cement hydration

Phosphogypsum (PG) is a residue from the fertilizer industry used by Portland cement companies as a source of calcium sulfate to control the setting time during the hydration (or hardening process). However, certain impurities can alter the cement hydration kinetics. Thus, this paper aims to analyze...
