• #### Cement clinker - Wikipedia

2021-5-13 · 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.

1979-3-1 · The liquid phase appears to play an important part in the clinker grindability; a higher liquid phase in the clinker shows a higher work index. The increase of liquid can be attributed to the increasing iron and alumina contents (fluxes) ; on rapid cooling the liquid present fails to crystallize and forms a glass instead, thus increasing the strength of the clinker.
