White cement's chemical composition and physical characteristics meet . Silica (S 1 O 2 ) = 20 to 25%. Ferrous Oxide (Fe 2 O 3 ) = 2 to 4%. The white color is obtained by the use of particularly pure raw materials and by a special firing and milling technique. The residential building is remarkable because of its height, nearly 1,400 feet, and small footprint, 93 feet square. The finer the grain contains - the more the need for cement.

Requirement of White Cement Raw Material. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. Argillaceous- This term refers to the Alumina. White mortar is also used for tile grout. It is prepared from raw materials free from Iron oxide and is a type of ordinary portland cement, which is white. However, the raw material mix is carefully chosen so as to minimize as far as possible the presence of compounds that have a colouring effect, such as chromium, manganese, iron, copper, vanadium, nickel and titanium. 9. Metakaolin was stored in a separate silo. In white cement manufacture, these raw materials are kept to least . Understanding White Cement Composition: White cement is created from raw ingredients that are devoid of colorants like Fe, Mn, Cr, and Ti. Aluminium Oxide (Al 2 O 3 ) = 4 to 8%. The cement is a typical low-alkali cement. Depending on the desired properties the mortar may further comprise a polycarboxylate ether based superplasticizer, a calcium sulfoaluminate cement, an oleate water proofing agent, an vinyl acetate-ethylene copolymer resin, cellulose ether, a defoaming agent and/or reinforcement fibers.
