摘要
The temperature influence factor on the kinetics of hydration of hemi hydrated calcium sulphate β has been studied in this work under microwave irradiation between 10℃ and 50℃ by isothermal calorimetry. Results show that the temperature corresponding to a maximum of the maximum rate of hydration or a minimum of tm, the existence of which could be shown theoretically and experimentally during the conventional hydration does not exist under microwave irradiation. This maximum rate or minimum of tm, is replaced by a limit (above 40℃) which has been determined and interpreted.
