Gypsum is added to powdered clinkers to get cement.

Gypsum is added to powdered clinkers to get cement. Addition of gypsum to clinker decreases its setting time and thus cement hardens readily on mixing with water. During the grinding process of cement, the clinker is mixed with 3-5 % of gypsum with certain dispersing and water proofing agents and then ground to a fine powder.

Cement clinker - Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
