  • What is Cement Clinker? Composition, Types Uses

    Clinker, when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely, produces cement. Clinker can be stored for long periods of time in a dry condition without degradation of quality, hence it is traded internationally and used by c ement manufacturers when raw materials are found to be scarce or unavailable.

  • Clinker quality depends on raw material composition.

    14-1-2014The resulting clinker (rounded nodules between 1mm and 25mm across) 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 quality depends on raw material composition.
