Raw Materials Used For Manufacturing of Cement

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

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.
