White cement is produced on the basis of lowiron clinker, where the content of manganese and chromium is minimized. It also includes mineral additives, limestone, gypsum, chlorinated salts, which give it a whitish color. Technology. Crushing of raw materials and grinding of clinker takes place in grinders / mills equipped with a special lining.
Apr 04, 2018 · As such, the amounts of these transition metal ions, particularly Cr 3+, Mn 3+, and Fe 3+, should be minimized to form white cement. Usually, Cr 2 O 3, Mn 2 O 3, and Fe 2 O 3 are kept below %, %, and %, respectively, in the clinker . Cheap quarried raw materials .
Alkalies : The most of the alkalies present in raw materials are carried away by the flue gases during heating and the cement contains only a small amount of alkalies. If they are in excess in cement, they cause a number of troubles such as alkaliaggregate reaction, efflorescence and staining when used in concrete, the brickwork of masonry mortar.
