    Dust emission from cement kilns can be a serious nuisance. In populated areas it is usual and often compulsory to fit cyclone arrestors, bagfilter systems, or electrostatic dust precipitators between the kiln exit and the chimney stack. Modern cement plants are equipped with elaborate instrumentation for control of the burning process.

    The comparative study of concrete properties made with and without cement kiln dust CKD blended cement was studied by Ramakrishnan 1986 by blending 5 CKD with 95 by weight of regular type I cement. Results showed that addition of cement kiln dust slightly retarded the setting times of cement and fresh concrete properties.

    Ravindrarajah 1982 reported that kiln dust could be used in masonry and concrete blocks without loss of strength or workability. His study showed that up to 15 of the Portland cement could be replaced with CKD. If higher percentages of dust were used, the setting was retarded, workability was reduced, and water demand was increased.
