Cement kiln dust (CKD) is a fine-grained solid by-product generated during the cement manufacturing process and captured by the facility's air pollution control system. Because much of the CKD is unreacted raw materials, it is often returned to the production process.

Influence of the composition of cement kiln

Cement kiln dust (CKD), a by-product of the cement industry, contains significant amounts of alkali, free lime, chloride and sulfate. Wide variation reported in the chemical composition of CKDs limits their potential application as a sustainable binder component in concrete.

US4268316A - Masonry cement composition -

A masonry cement is prepared by blending portland cement, kiln dust, and fly ash. The cement of this invention exhibits no efflorescence, good board life, workability, and acceptable color for use with such construction materials as brick, cinder block, and concrete block.

Portland cement - Wikipedia

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker

Cement Kiln Dust (CKD): Characterisation and

Cement kiln dust (CKD) is a by-product of the cement manufacturing process. Despite the fact that usually its composition is similar to partially calcined raw feed, the variability in raw materials, fuel, type of process, dust collection systems and product specifications influence both the physical and chemical characteristics resulting in a highly variable material.
