Cement manufacturing process: Step-by-step guide -

2020-7-20  Cement manufacturing process in summary. Portland cement is manufactured by heating limestone (calcium carbonate) with other materials (such as clay) to 1,450 °C (2,640 °F) in a kiln, in a process known as calcination that liberates a molecule of carbon dioxide from the calcium carbonate to form calcium oxide, or quicklime.
