Cement kiln dust (CKD) is a finely-divided particulate material carried in the air stream of a cement kiln and removed by the plant's air pollution control system. In essence, any given CKD is a mixture of airborne particles of cement-making raw materials, partly-processed cement grains, and volatile components condensed on their surfaces.

The activator content is generally in the range of 20 to 30 percent of the fly ash used to fill the voids. The activator is normally either lime or Portland cement, but lime kiln dust or cement kiln dust can also be used. Similarly, consider a clay soil that is stabilized with lime but the clay is not pozzolanically reactive.

An experimental work was conducted to study the use of factory-waste roof shingles to enhance the properties of fine-grained soil used in road works. Cement kiln dust (CKD), a cogenerated product of Portland cement manufacturing, was used as a stabilizing agent while the processed shingles were added to enhance the soil tensile strength. The effects of shingles on strength and stability were ...
