SuStainable cement productionCement and concrete manufacturing: the process The main component of cement is clinker. Clinker is produced from raw materials, such as limestone and clay, which are crushed, homogenised and fed into a rotary kiln. The clinker burning takes place at a material temperature of 1450°C which is needed to form the new compounds.
