Gypsum processing and use

Gypsum rock is converted into gypsum plaster by driving off some of the chemically combined water. Heating gypsum at 120°C for one hour results in a hemi-hydrate (CaSO 4.1⁄2H 2O) – with three quarters of the water removed. Gypsum hemi-hydrate is also known as Plaster of Paris. Prolonged heating over several hours results in the formation of

"Gypsum" and "Gypsum Board"

Why Gypsum is Fire Resistant. Gypsum is strong against fire. The secret is in crystallized water equivalent to about 21% of its weight. This crystallized water is very stable in normal condition and does not disperse, but once it comes in contact with the heat of fire it will cause thermal decomposition and start to evaporate. The temperature of gypsum does …
