PORTLAND CEMENT MANUFACTURING RESIDUAL

Portland cement manufacturing is an energyintensive process that grinds and heats a mixture of raw materials such as limestone clay sand and iron ore in a rotary kiln That product called clinker is cooled ground and then mixed with a small amount of gypsum to produce cement.

Portland Cement an overview ScienceDirect Topics

Production of Cement Portland cement is a complex mixture of compounds formed from the oxides of calcium CaO silicon SiO 2 aluminium Al 2 O 3 and iron Fe 2 O 3 In addition to these four main constituents it also contains smaller amounts of magnesium oxide MgO and oxides of the alkali metals potassium K 2 O and sodium Na 2 O.
