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 2-6 % gypsum Raw Materials Necessary for Portland Cement Manufacture .
Sometimes, effects similar to those achieved through the addition of admixtures can be achieved by altering the concrete mixture-reducing the water-cement ratio, adding additional cement, using a different type of cement, or changing the aggregate and aggregate gradation. Five Functions Admixtures are classed according to function.
Or you can use a CCG plant to increase the grinding capacity at your existing production facilities. To make it even more versatile, you can specify additional equipment that will expand the standard CCG plant into a stand-alone system that can handle the complete grinding and cement-loadout process.
