Cement Kilns: Clinker Minerals

Clinker Phases. Portland cement clinker is a "phase assemblage" in which the main mineral crystalline species are: Alite - roughly Ca 3 SiO 5; Belite - roughly Ca 2 SiO 4; Tricalcium Aluminate - roughly Ca 3 Al 2 O 6; Tetracalcium Aluminoferrite - roughly Ca 2 (Al,Fe) 2 O 5

Cement Clinker - Imerys Performance Minerals

Imerys provides a variety of raw material additives that are used to enhance the properties of portland cement. Portland cement is produced by sintering (fusing together without melting to the point of liquefaction) limestone, sand, and aluminosilicate materials such as Kaolin clay to produce cement clinker. Clinker is then ground with additives, such as limestone and gypsum, to form Portland cement.

Cement - Wikipedia

By far the most common type of cement is hydraulic cement, which hardens by hydration of the clinker minerals when water is added. Hydraulic cements (such as Portland cement) are made of a mixture of silicates and oxides, the four main mineral phases of the clinker, abbreviated in the cement chemist notation, being: .
