Abstract
AbstractStudies were made of the effects of temperature, duration of heating and intergranular movement during the dehydration of gypsum in vacuo, on the reactivity of the resultant calcium sulphate hemihydrate. The formation of orthorhombic anhydrite was not associated with a significant increase in reactivity. The results are discussed in terms of variations in the population of seeding nuclei for the growth of gypsum.The kinetics of the formation of orthorhombic anhydrite from soluble anhydrite formed from gypsum in vacuo are significantly different from those found when soluble anhydrite has been formed by dehydrating calcium sulphate hemihydrate.
