Cement manufacturingraw materialsUnderstanding 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.

CementWikipedia
A cement is a binder a substance used for construction that sets hardens and adheres to other materials to bind them together. Cement is seldom used on its own but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry or with sand and gravel produces concrete.Concrete is the most widely used material in existence and is behind only water as
