Continuous monitoring of calcium sulfate hemihydrate and dihydrate X-ray diffraction peaks was done to determine the kinetics of gypsum-product formation during the setting of plaster mixtures containing various concentrations of accelerators and retarders. Amounts of product formation were then correlated to Gillmore setting times and to compressive strengths.
