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 practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

Cement Composition - an overview ScienceDirect Topics

The effect of cement composition on cement strength has been studied extensively. 177,182,189,400,420 It appears that this effect is a rather complex one and depends on a variety of factors such as the mutual ratios of clinker minerals, the amount and form of added calcium sulfate and the presence of minor oxides. The available experimental data may be summarised as follows.
