Gypsum is the essential mineral component of plasters and drywall. It is a soft sulfate mineral composed of calcium sulfate dihydrate. When mixed with water, it forms a paste that hardens over time and is commonly used in construction materials such as plaster, drywall, and plasterboard. Talc is also used in some construction materials, but it is not as essential as gypsum. Garnet and apatite are not commonly used in construction materials.
