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.

Deep decarbonisation within the process. The formation of carbon dioxide during the calcination reaction is unavoidable and can account for up to 65% of carbon dioxide emissions from cement production. "Capture of the carbon dioxide is an option and retrofitting carbon capture equipment to cement plants is conceivable," says d'Hubert.

Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...

The cement production process begins with the extraction of limestone and clay from the quarry. The material is then blended, crushed and fed to the kiln. Post-kiln, the clinker is cooled and goes through a final grinding method before it is ready to ship. Portland cement, the most common type of cement, is formulated in a variety of strengths ...
