Evaluation of Tikrit Dune Sand Soil Enhanced with CKD

Dune sands occupy large parts of Iraq, posing significant challenges for infrastructure building. Geotechnical research and stabilization dune soils are necessary to determine the engineering features these as a foundation material in consideration global growth construction activities, especially Iraq. The compressibility collapsibility key soil design works, which must be carefully analyzed. In this study, selected geotechnical properties, including compaction, compressibility, characteristics, compacted samples from city Tikrit were evaluated laboratory using specific range “cement kiln dust (CKD)” concentrations stabilizing agent. amounts CKD used study 4, 8, 12, 16, 20% by dry weight soil. results showed that adding improved compaction decreased amazingly eliminated collapsibility. quality treated with is very high, it recommended use works.
