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.
