The Cement Manufacturing Process - Advancing Mining
The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction.

Autoclave expansion is another property of cement that partly depends on the grinding process. More often, it is experienced that cement ground in the laboratory mill shows higher autoclave expansion than the cement produced in the plant mill, even when both of them are having equal amount of gypsum and ground to the same specific surface area.
