production of portland cement

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). It is produced by heating together naturally occurring raw …
