Cement Raw Materials used in Manufacturing of Cement
This makes the cement sound if present in small quantity but an excess can make the cement unsound. Cement is sometimes blended with other cementitious and/or a special material. This cement is called blended cement. They are produced by properly blending two or more types of cementitious materials and cement raw materials.

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 RAW MATERIALS International Cement Review
The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns.

Composition of cement
This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000 o F to 2,600 o F). It hydrates rapidly, but does not contribute much to strength of the cement paste. By mixing these compounds appropriately, manufacturers can produce different types of cement to suit several construction environments.
