Zusammenfassung:The process of hydration and hardening of theanhydrite,and the condition of practical use of itsproducts have been studied by way of the thermodyna-mic calculation.The calculated results show thatthe hydration reaction of anhydrite is a spontaneousprocess and follows the dissolution-crystallizationmechanism it is also shown that the drying-curingtemperature of the anhydrite products can not behigher than 85℃ and the temperature of practicaluse of its products can’t be higher than 48℃ underthe moist environment.
