Flue dust, portland cement 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@Ca(OH)2@Feldspars@CaSO4@Fly ash@KCl@Iron oxides@K2CO3@CaF2@K2SO4@CaO@Na2SO4@Glasses of SiO2, Al.s@Portland cement chemicals [659

Cement, portland, chemicals Portland cement is a mixture of chemical substances produced by burning or sintering at high temperatures (greater than 1200°C (2192°F)) raw materials which are predominantly calcium carbonate, aluminium oxide, silica, and iron oxide. The chemical substances which are manufactured are confined in a crystalline mass. This category includes all of the chemical substances specified below when they are intentionally manufactured in the production of Portland cement. The primary members of the category are Ca2SiO4 and Ca3SiO5. Other compounds listed below may also be included in combination with these primary substances.@CaAl2O4@Ca2Al2SiO7@CaAl4O7@Ca4Al6SO16@CaAl12O19@Ca12Al14Cl@Ca3Al2O6.@Ca12Al14F2@Ca12Al14O@Ca4Al2Fe2.@CaO@Ca6Al4Fe2.@Ca2Fe2O5.

Cement, alumina, chemicals High-Alumina cement is a mixture of chemical substances produced by burning or sintering at high temperature (greater than 1200°C (2192°F)) raw materials which are predominantly calcium carbonate, aluminium oxide, silica, and iron oxide. The chemical substances which are manufactured are confined in a crystalline mass. This category includes all of the chemical substances specified below when they are intentionally manufactured in the production of high-alumina cement. The primary members of this category are CaAl2O4, Ca4Al2Fe2O10, Ca12Al14O33, and Ca2SiO4. Other compounds listed below may also be included in the combination with these primary substances.@CaAl4O7@Ca2Al2SiO7@CaAl12O19@Ca4Al6SO16@Ca3Al2O6.@Ca12Al14Cl@CaO@Ca12Al14F2@Ca3SiO5@Ca6Al4Fe2.@Ca2Fe2O5.
