Cement Manufacturing Process: How the Cement is Made?

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 Raw Materials used in Manufacturing of Cement

Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale.

How is fiber cement board manufacture

Fiber cement board manufacturing process also makes use of autoclave technology. In autoclave technology, polymer based composites are manufactured by applying intense heat and pressure to eliminate moisture from fibre cement materials. This leads to composite consolidation and the result is an extremely strong and robust fibre composite material.
