Manufacturing Process Of Ordinary Portland Cement (Opc)

Manufacturing Process Of Ordinary Portland Cement (Opc)

The manufacturing process of Ordinary Portland cement is made primarily from calcareous and argillaceous materials, such as limestone or chalk, and from aluminium oxide, silica oxide, ferric oxide and magnesium oxide found as clay or shale. Raw materials for the manufacture of Portland cement are found in nearly all countries and cement plants operate all over the world.

Manufacture Of Portland Cement

Manufacture Of Portland Cement

The raw materials used in the manufacture of Portland cement consist mainly of lime, silica, alumina and iron oxide. These compounds interact with one another in the kiln to form a series of more complex products and, apart from a small residue of uncombined lime which has not had sufficient time to react, a state of chemical equilibrium is reached. The resultant of firing is the clinker.
