Abstract
To determine the geotechnical properties of Stabilized dune sand by Using Cement Kiln Dust (CKD) and to assess the suitability of resting shallow foundation on it, an extensive laboratory testing program was carried out. The results indicated that: Cement kiln dust (CKD) caused an irregular decrease in the liquid limit when it was mixed with sand. The mix of CKD allowed compaction of the soil at lower maximum dry unit weight and higher optimum water content. Cement dust caused an increase in ö and (c). The variation in shear strength parameters became almost constant after fourteen days of curing. Stabilization of collapsible soils with CKD can provide tremendous economical advantages.
