THE CEMENT MANUFACTURING PROCESS Prof. Dr Elshafie Ahmed Gad Faculty of Applied Science Chemistry Dept. Portland Cement Portland cement is made by mixing substances containing CaCO3 with substances containing SiO2, Al2O3, Fe2O3 and heating them to a clinker which is subsequently ground to powder and mixed with 26 % gypsum Raw Materials Necessary for Portland Cement .
Process of Manufacturing of Cement The cement is manufactured by integrating the calcareous component and argillaceous component in ratio of 3 : 1. The calcareous component can be limestone, chalk, marine shells, marl whereas argillaceous components can be shale, clay, blast furnace slag, slate.
Cement manufacturing process. What is cement? Cement is a fine powder which sets after a few hours when mixed with water, and then hardens in a few days into a solid, strong material. Cement is mainly used to bind fine sand and coarse aggregates together in concrete. Cement is a hydraulic binder, it hardens when water is added.
