Cement Kiln - an overview | ScienceDirect Topics

Cement kiln dust (CKD) is an industrial waste material collected from cement kiln exhaust gases during Portland cement production. In the production of Portland cement, clay and calcium carbonate are finely ground, mixed and calcined at 1450 °C. During this process, calcium silicate is the main product formed and a dust named CKD is generated.
