Cement clinker - Wikipedia OverviewComposition and preparationUsesClinker grinding aidsClinker minerals hydrationContribution to global warmingSee alsoCement 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 aluminosili e materials such as clay during the cement kiln stage.
