Cement Kilns: Clinker Minerals

Of the many calcium aluminate minerals, this has the highest calcium content, and is the only one normally present in Portland clinker, although early cements could contain mayenite (roughly Ca 6 Al 7 O 16.OH). As an interstitial phase, its crystals grow to fit into

Cement Clinker - Imerys Performance Minerals

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. Kaolin clays can be used as a source of alumina.

Portland cement clinker - Understanding Cement

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

Cement clinker - Wikipedia

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.
