Detailed Solution

Concept: Gypsum is found to be a naturally occurring mineral. It is made up of calcium sulphate in a hydrated form. Its molecular formula is

C a S O 4 .2 H 2 O

.
Gypsum is added to cement in order to reduce the rate of setting of cement by reducing the rate of hydration and thereby, giving hardness and strength to the cement.
During the method of manufacturing cement, there is the production of clinkers. These clinkers are cooled and then mixed with a small quantity of gypsum and then finally ground for the last time.
Hence, Gypsum is added to clinker for manufacturing cement in order to decrease the rate of setting of cement.
Hence, the correct answer is option 1.
