· Cement clinker is a solid material made during the production of Portland cement. It is formed by heating a mixture of raw materials, including limestone and clay, to high temperatures in a kiln. The resulting clinker consists mainly of four minerals: alite, belite, tricalcium aluminate and calcium aluminoferrite.

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

Clinker is the most common rocktype found in burning coal mining dumps and is usually red or pink, less commonly yellow or white in colour. It is usually composed of quartz, feldspars, mica and minor mullite. White clinker-like rocks are sometimes called porcellanites, though this can have widely varying definitions.
