What is Flue dust, portland cement ?

Definition

Flue dust, portland cement is a complex combination of finely divided inorganic particles separated from the exit gases formed during the manufacture of Portland cement. The flue dust consists of uncalcined raw materials along with partially calcined materials. Some Portland cement clinker is usually included. The major constituents of kiln dust are calcium carbonate, clays, shales, quartz and sulfate salts. The following materials may also be present:: Dolomite; Feldspars; Fly ash; Iron oxides; CaF2; CaO; Glasses of SiO2, Al2O3 and Fe2O3; Ca(OH)2; CaSO4; KCl; K2CO3; K2SO4; Na2SO4; Portland cement chemicals [65997-15-1*]
