Gypsum in the form of the dihydrate (CaSO4·2H20) or the hemihydrate (CaSO4 ·½ H20) is an important additive in cement is. It serves to retard the setting and hardening of the cement. In the quality control of cement, it is therefore important to know the exact content of .
What is the purpose of calcium sulfate (gypsum)? A. For modern cements, the rate of stiffening of the cement paste should be controlled within limits to make the cement a useful product. If the reactions were too rapid, causing flash set, the concrete would stiffen too quickly. If too slow, the delay in acquiring strength would be objectionable.
In such appliions as stucco and plaster, cement and lime may be substituted for gypsum; brick, glass, metallic or plastic panels, and wood may be substituted for wallboard. Gypsum has no practical substitute in the manufacturing of portland cement. Synthetic gypsum generated by various industrial processes, including FGD of

· Gypsum is obtained from inorganic rocks that encompass ironic deposits of calcium sulphate. Gypsum plaster is used in interior plastering. In time past, plastering is done through the mixture of sand, cement and water. But now, plaster of Paris which is also known as gypsum plaster is gradually replacing this process of sand, cement and water.
Gypsum is a naturally formed mineral that is already known to be added to cement at small percentages in order to reduce the speed of reaction with water, however it seems that substantial technical research has not been done concerning larger proportions of gypsum.
