11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these

Dehydration of the gypsum added to the cement In the grinding process heat will be generated and the cement will be heated up. The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process.

Cement. A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together Cement is seldom used on its own, but rather to bind sand and gravel togetherCement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concreteConcrete is the most widely used material in existence and is only behind ...
