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.

The country has now taken on a new level, becoming an exporter of cement clinker. Cement & Clinker. For clarity, cement and clinker are different in their uses.
How to Make Cement Clinker Cement clinkers are formed by the heat processing of cement elements in a kiln Limestone, clay, bauxite, and iron ore sand in specific proportions are heated in a rotating kiln at 2,770 Fahrenheit (1,400 Celsius) until they begin to form cinder lumps, which are also known as cement.
Arthur Michael Harrisson, in Lea's Chemistry of Cement and Concrete (Fifth Edition), 2019. 184.108.40.206 Blastfurnace Slag. Where it is not appropriate to use blastfurnace slag as a cementitious material, the composition and origin of slag provides a potential raw material for clinker production.Most raw materials for cement manufacture are quarried and prepared for firing in the cement kiln at a cost.
The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction.
Clinker can be substituted with other cement-like materials, including waste from coal combustion and steelmaking. This can affect the cement’s properties, however, so is only suitable for some end uses. The world average clinker ratio (clinker:cement) fell to 0.65 in 2014, with a large range from 0.57 in China to 0.87 in Eurasia.
