The terms cement and concrete are used interchangeably, although cement is actually an ingredient of concrete. Gypsum is often added to cement and concrete to slow down the drying time. Cement dries quickly and retarding that process allows workers to pour the mixture into the various forms or frames needed.
Gypsum plays a crucial role in cement. Though it is used in a small quantity, in the range of 2.5-3.0 percent in terms of SO3, gypsums role in cement is significant, more predominantly at early ages.
If a Thistle finish plaster is applied before the shrinkage is complete there is an increased risk of delamination or cracking of the finish, particularly if the undercoat was not thoroughly keyed. The key provided to cement-based undercoats needs to be much deeper and the drying time allowance much longer than for gypsum-based undercoats.
