GYPSUM
Gypsum (CaSO4.2H2O) is a naturally occurring mineral mined from deposits formed by ancient sea beds as a raw material, white when pure, but commonly grey, yellow, red or brown, owing to impurities. The anhydrous form (CaSO4), anhydrite, is common.
Most gypsum is calcined and used in the manufacturing of plaster products. Wallboard and plaster requires gypsum contents greater than 85%, although producers prefer a minimum of 94–95% along with whiteness in color. The major consumers of the Gypsum at present are Cement Industry. By weight about 4% to 6% Gypsum in crushed condition is utilized in Portland Cement Manufacture after mixing with cement/clinker. Gypsum acts as a retarder and controls the setting time of cement.
There are two variations of gypsum: natural, which can be found while mining sedimentary rocks; and chemical, which is a by-product of phosphate chemical fertilization and energy production.
for producing cement. Due to having fire-resistant qualities, it has been the material of choice for building structures since ancient times.

Indian Cement producers particularly located in Central, Eastern and Southern India are dependent on the import of high quality Natural Gypsum, mainly from Thailand and Sultanate of Oman.
