Why is gypsum used in cement ?

Description : Why is gypsum used in cement ?

Last Answer : Gypsum is used to make cement slowly solidify. When the cement solidifies too fast, the amount of space inside the cement increases , the cement setting becomes weak and brittle. The use of gypsum in cement strengthens the setting of cement. As a result the cement is hard and long lasting.

How does the setting of cement takes place & what is the role of gypsum in setting of cement ?

Description : How does the setting of cement takes place & what is the role of gypsum in setting of cement ?

Last Answer : Ans When mixed with water, the setting of cement takes place to give a hard mass. This is due to the hydration of the molecules of the constituents and their Rearrangement. The purpose of adding gypsum is only to slow down the process of setting of the cement so that it gets sufficiently hardened.
