In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. 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.

Role of Gypsum in Cement and its Effects
The group reported that gypsum actually forms in a three-step process: precipitation of nanocrystals of bassanite — or calcium sulfate hemihydrate, with one water molecule for every two calcium sulfate units — followed by the assembly of those crystals into larger aggregates, and finally transformation of the aggregates into gypsum.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including ...
