Product Description

Cement clinker is a solid material that is produced in the manufacture of Portland cement. It is formed by heating a mixture of limestone and clay to high temperatures in a kiln. The resulting clinker consists mainly of four minerals: alite, belite, tricalcium aluminate and calcium aluminoferrite. These minerals have different properties and react with water to form the cement paste that binds the aggregates in concrete. Cement clinker is ground to a fine powder and mixed with gypsum to control the setting time of the cement.
