Natural Gypsum Gypsum is a mineral found in natural rock. It is extracted either by quarry ing or mining. Pure gypsum contains 79.1% calcium sulfate (CaSO 4) and 20.9% chemically bound water (H 2O). However, since gypsum is a natural material, pure gypsum is rarely found. Natural gypsum typically contains up to 15 to 20% impurities such as lime,

After mining, the gypsum is processed into a variety of products, the most common of which are wallboard and plaster-of-Paris. To produce wallboard, the gypsum is calcined, an industrial term for the process that includes the grinding of gypsum to a fine powder which is then heated for 2 to 3 hours. During the heating process, the powdered ...

Gypsum deposits occur in many countries, but Spain, Thailand, the United States, Turkey, and Russia are among the leading producers. The largest gypsum crystal was found in the Braden mine in Chile and exceeds 3 metres (about 10 feet) in length and 0.4 metre (about 1.5 feet) in diameter. In the U.S., commercial sedimentary gypsum deposits occur in New York and …

Nov 23, 2017 To investigate the crack behaviour of rock or rock-like material in uniaxial loading, a series of numerical simulations were conducted on gypsum specimens containing a single flaw with different inclination angle (0–90) and length (10 mm–30 mm). Based on the numerical simulations results, the effect of flaw length on peak strength, the CI stress, and the CD stress …
