What is Cement Clinker? | Datis Export Group

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 clinker - Wikipedia

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.

Although China has one of the lowest clinker-to-cement ratios globally, its ratio rose rise from 0.57 to 0.60 during 2014‑17, then to 0.64 in 2018. The main causes are overcapacity, which reduces momentum for more blending to replace clinker, and changes to cement standards, which have eliminated a grade of composite cement.
