Cement Manufacturing Process: How the Cement is

All the cement plants set up after 1980 use the dry process for the manufacture of cement. In this process, the calcareous materials such as limestone are crushed and stored in silos or storage tanks. The argillaceous material such as clay is thoroughly mixed with water in a container known as the wash mill. This washed clay is stored in basins.

Cement manufacturing - raw materials -

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.

Difference between OPC and PPC Cement-

Heat is generated when water and cement react with each other. In the case of OPC hydration process takes less time for completion and it produces more heat than PPC: Where in case of PPC cement, hydration process takes longer time and produces less heat during hydration. So, it can be used for mass concreting.
