Cement kiln dust

Calcination is the main process of clinker production, calcining calcium carbonate (CaCO 3) at about 900 °C to form calcium oxide, CaO, lime, and the release of carbon dioxide gas (CO 2).In the next step of the so-called clinker treatment, calcium oxide (CaO) is exposed to temperatures of 1400 °C to 1500 °C together with silica (SiO 2), …

Alternative Clinker Technologies for Reducing Carbon …

The calcium silicate compositions created in the rotary kiln emerge in a "clinker" form, that is, in small granules with diameters of approximately 1 to 4 mm. The clinker is then ground to a powder with a mean particle size of approximately 12 μm. To produce concrete, this material is mixed with aggregates, sand and water.
