Clinker quality depends on raw material composition.

Portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then are recombined into new compounds.
