Gypsum - Wikipedia

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall. A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval EnglandPhysical and mechanical properties of gypsum,22-04-2010· Physical and mechanical properties of gypsum-cement particleboards were analyzed for specimens previously conditioned at 20 °C and 60% relative humidity and then soaked in water for 24 hours.
