The alumina and iron act as fluxing agents which lower the melting point of silica from 3,000 to 2600º F. After this stage, the clinker is cooled, pulverized and gypsum added to regulate setting time. It is then ground extremely fine to produce cement.

The Hydration Reactions. Each of the four main cement minerals reacts at a different rate and tends to form different solid phases when it hydrates.
Gypsum is an ingredient in the manufacture of portland cement, added to control the setting time of the concrete. Gypsum is added to the cement clinker from the kiln and the mixture is processed to a fine powder. The typical gypsum content of portland cement ranges from 5 to 10%.
A small amount of gypsum (3 percent to 5 percent) is added to the clinker to regulate how the cement will set. The mixture is then very finely ground to obtain "pure cement.". During this phase, different mineral materials, called "additions," may be added alongside .
