    Cement manufacturing - raw materials - Understanding Cement

    Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In pract, however, clinker composition is largely determined by the compositions of the locally-availe raw materials which make up the bulk of the raw meal.
