The rate of production of gypsum plaster by a continuous calcination process, in which a mass of gypsum being calcined is maintained in a fluidized condition predominantly by the water vapour evolved during calcination, can be considerably increased and a plaster product of reduced water demand be obtained by introducing an aridizing agent such as calcium chloride along with the gypsum .
Gypsum binders are energy-saving materials because calcination processes oc- cur at significantly lower temperatures than they do with cement and lime, usually within a range of 135180C.
