Portland cement clinker is ground to a fine powder and used as the binder in many cement products. A little gypsum is sometimes added. It may also be combined with other active ingredients or chemical admixtures to produce other types of cement including: ground granulated blast furnace slag cement pozzolana cement silica fume cement Clinker, if stored in dry conditions, can be kept for ...

Fly ash cement was developed from a mixture of Portland cement and fly ash as a hydraulic binding agent. In laboratory investigations, fly ash cement was produced by homogenizing Portland cement, clinkers, and fly ash as well as by grinding Portland cement, clinkers, gypsum and fly ash together. The experiments indicate that grinding the components together gives higher compressive strength ...
When is Gypsum added in the cement ? In the manufacture process of cement, clinkers are formed. These cement clinkers are cooled down and added with small amount of gypsum. The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 2.5%.

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

This is another variety of low heat cement. Its standards exist under B.S but not under A.S.T.M. it is made by grinding about 70-80% B. F. Slag with about 10% gypsum and 1-2 % Portland clinker or lime. This cement is also middy resistant to sulphate attack.
Grinding the clinkers with gypsum. The cement clinkers are then air-cooled. The required amount of gypsum (2.0 %) is first ground to a fine powder and then mixed with clinkers. At this stage finished cement is pumped pneumatically to storage silos from where it is drawn for packing in paper bags or for dispatch in bulk containers. Setting of cement

Gypsum and calcium carbonate are relatively soft minerals, and rapidly grind to ultra-fine particles. Grinding aids are typically chemicals added at a rate of 0.01-0.03% that coat the newly formed surfaces of broken mineral particles and prevent re-agglomeration. They include 1,2-propanediol, acetic acid, triethanolamine and lignosulfonates.
Clinker. Cement clinkers are formed by the heat processing of cement elements in a kiln. Limestone, clay, bauxite, and iron ore sand in specific proportions are heated in a rotating kiln at 2,770° Fahrenheit (1,400° Celsius) until they begin to form cinder lumps, which are also known as cement clinkers.

Grinding: The cooled clinkers are finally ground in ball mills or tube mills. Also, the gypsum is added during grinding about 2-4% . The gypsum acts as a retarder and so allows the cement to mix with sand or aggregate and to be placed in postion. i.e. it increases the initial setting time of cement.
