Clinker is a dark grey material with 3 to 25 millimeters in diameter and is produced by heating clay and limestone in the temperature of 1400°C to 1500°C. It can be kept in stores for a long time without any change in its quality. Cement manufacturers buy clinker for producing cement in areas where there is not enough raw materials.
The main features of these cement ingredients along with their functions and usefulness or harmfulness are given below: Lime : Lime is calcium oxide or calcium hydroxide. Presence of lime in a sufficient quantity is required to form silicates and aluminates of calcium.

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.
5. Cement grinding. At the cement mills the clinker is mixed with other additives required for producing the specific type of cement. Gypsum for OPC, limestone for limestone cement, and slag for slag cement. The ball mill then grinds the feed to a fine powder. The fine powder is then sent to a separator which separates fine and coarse product.
Gypsum slows down the hydration rate of C 3 A. Cement low in C 3 A is sulfate resistant. Tricalcium silicate, C 3 S:This compound hydrates and hardens rapidly. It is largely responsible for portland cement''s initial set and early strength gain. Dicalcium silicate, C 2 S: C 2 S hydrates and hardens slowly. It is largely responsible for ...
