Cement kiln dust is fine particles similar in appearance to Portland cement. If the clinker production takes place in a wet process, the dust is collected in the form of a suspension, if the clinker production is dry, the dust is collected in a dry form.
Cement kiln dust, on the other hand, gets rid of extra step, as the initial mixing and compacting is enough to stabilize the material sufficiently (Miller and Zaman, 2000). Cement is often used for soil stabilization in transportation construction. Cement kiln dust is an effective alternative to cement, which is more expensive than finer CKD.
In 1990, the cement industry generated an estimated 12.7 million metric tons of cement kiln dust from 111 plants in 38 states, 4 million metric tons of which were disposed of in piles, quarries, and landfills. In 1995, the industry disposed of an estimated 3.3 million metric tons of cement kiln dust.
