How to Improve the Quality of Cement Clinkers

The primary raw materials used in a cement clinker are limestone and clay, which are ground into fine powdery form. The powdered raw material which is called raw meal is then subjected to a high temperature at about 1450 degrees in a cement kiln.

Raw materials - Understanding Cement

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. Supplementary materials are used to adjust the composition of the raw meal but cost and availability are likely to determine the extent to which they are used.
