Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is commonly found in sedimentary rock formations and is often associated with other minerals such as anhydrite, halite, and sulfur. The name "gypsum" is derived from the Greek word "gypsos," which means "plaster" or "chalk."

Mar 1, 2017 · This reduction is directly related to the density of EPS (Fig. 7). In addition, as tragacanth addition ratios increase, their density values decrease, which is caused by the artificial pores that occurred later.
