We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.

It may pass directly to the cement mill. At the cement mill, the clinker is further grinded into a very fine powder and then gypsum is added in a very small amount. The gypsum is used to control the initial and final setting time of cement. Manufacturing of cement is a very critical process because there are more than 25 types of cement.

Grinding- The klinkers, so obtained from the rotary kiln, are ground to the required degree of fineness in a ball mill or a tube mill.During grinding, a small quantity of gypsum (about 3% to 4%) is added. Gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set soon as water is added to it. thus, gypsum acts as a retarder, and delays the initial setting ...
