Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO·2HO). It is widely recognized for its versatility and is commonly found in sedimentary rock formations. The primary use of gypsum is in the construction industry, where it is a key ingredient in the production of plaster, drywall (also known as gypsum board or sheetrock), and cement. Gypsum's ability to harden when mixed with water makes it ideal for creating smooth wall finishes, ceiling tiles, and as a fire-resistant barrier in building materials. Additionally, it is used in agriculture as a soil conditioner to improve soil structure and nutrient availability.
