What is Cement Clinker? Composition, Types & Uses - Civil Engineering
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.

Cement manufacturing generates large amounts of CO2 during a physical-chemical process called "decarbonation". In this process, limestone is heated to very high temperatures to produce clinker, which then is ground down to produce cement. However, the amount of clinker required can be reduced by substituting alternatives called cement admixtures.
