Cement Kiln Dust as Partial Replacement of Cement for Improvement of Sabkha Soils for road application
View through CrossRef
Salt-encrusted desert flats or sabkha soil, which particularly formed in arid and semi-arid zones, have raised a noticeable concern because of low bearing capacity and high compressibility. this study is aimed to explore the feasibility of stabilizing Omani sabkha using environmentally friendly stabilizer through Cement Kiln Dust (CKD). Untreated and treated sabkha were characterized using standard proctor compaction test, unconfined compressive strength (UCS) and California Bearing ratio test (CBR). Results show that utilizing 7.5% binder that contained 50% Cement Kiln Dust improved the overall properties of sabkha soil and it can be used as sub-base layers.
