Gypsum is widely used in the construction materials industry:

(1) Use gypsum as a cementitious material for the preparation of gypsum-based mortar, such as wall plaster, adhesive plaster and gypsum-based self-leveling mortar;

(2) Use gypsum for the processing and production of gypsum products, mainly including paper-faced plasterboard, fiber plasterboard and decorative plasterboard.

(3) Use gypsum as the retarding agent in the production of cement and cement products.
