Cement Clinker

Cement Clinker

Cement Clinker is a key component in the production of cement, formed during the initial stage of cement manufacturing. It is a nodular material produced by heating a mixture of limestone (calcium carbonate) and other materials such as clay or shale in a kiln at high temperatures, typically around 1400 to 1600°C (2552 to 2912°F). The intense heat causes the raw materials to chemically react and fuse together, forming hard, granular pieces known as clinker.

The clinker nodules are usually grayish in color and have a porous, irregular texture. After cooling, the clinker is ground into a fine powder to produce cement, which can then be mixed with water, sand, and aggregates to form concrete. The grinding process may also include the addition of gypsum, which helps control the setting time of the cement.
