Moses GK, Saminu A. Cement Kiln Dust Stabilization of Compacted Black Cotton Soil. EJGE, 2012; 17-Bundle F: 825–833p. Al Karagooly HJ. Effect of Cement Kiln Dust on Some Properties of Soil. JBU: Eng. Sci. 2012; 20(4): 1100–07p
Accidental or deliberate operational discharges of organic chemicals or wastes containing organic chemicals induce geochemical reactions with resultant adverse effects on basic geotechnical properties of the soil. To utilize soil materials from such sites for engineering construction or as foundation soil, stabilization must be carried out. In this study, cement kiln dust (CKD) was applied to
This research investigated the suitability of cement kiln dust (CKD) on the stabilization of clayey soil extracted along a failed road section of Sango, Ota. Since CKD does not need any further processing or treatment, it is cheap as it is a waste product from cement production and can be utilized in powdery form. The suitability of CKD as a stabilizer is dependent on its performance on
Carbon sequestration through the formation of carbonates is a potential means to reduce CO 2 emissions.
