Abstract
A laboratory study was undertaken to evaluate the effectiveness of cement kiln dust (CKD) as a soil stabilizer. The study revealed that increases in the unconfined compressive strength (UCS) of soil occurred with the addition of CKD. Increases in UCS were inversely proportional to the plasticity index (PI) of the untreated soil. Significant PI reductions occurred with CKD treatment, particularly for high PI soils. Measurements indicate that the change in pH of soil as a function of CKD content is related to the PI of the untreated soil, and good correlation between pH response and ...
