Physical properties of calcined gypsum Semantic

Gypsum plaster is a flocculated suspension and the water requirement of calcined gypsum is related to the yield value of the suspension it forms in water. The strength of the structure that forms in the suspension will determine the yield value. The effects of physical factors such as temperature, entrained air and stirring on the water requirement are discussed.
