Raw materials used for its production:
Limestone: rocks comprising of minimum 90% CaCO3 (calcium carbonate).
Marn: Limestone having silica, clay materials and iron oxide.
Iron ore: Iron ore being in the form of hematite in nature is used as the ripening facilitator in cement industry.
Bauxide: Bauxide comprising of SiO2 and Al2O3 and being an aluminum ore is used as aluminum concentrator.
Raw meal: It is the homogenous mixture comprising of oxide of raw materials obtained by grinding limestone, marn, iron ore and Bauxide (CaO, SiO2, Al2O3, Fe2O3 and little other oxides).
Portland cement clinker: It is obtained by sintering raw meal comprising of CaO, SiO2, Al2O3 and other components at about 1450°C temperature. It is the hydraulic material comprising of clinker phases containing aluminum and iron and minimum 2/3 calcium silicate by mass and other components
