Abstract: The present investigation to assess the properties of concrete containing cement kiln dust (CKD).Concrete specimens were prepared with 0% CKD, 10% and 20% CKD as a replacement of cement weight, 10% and 20% CKD.Ordinary Portland cement (O.P.C., 53 grade) was used throughout this investigation.The properties of concrete specimens were evaluated by measuring workability (using slump test), compressive strength, split tensile strength and Flexural Strength..The compressive strength increased in the concrete mixtures including 10% CKD (as an addition of cement weight) and 5%, 10% Silica fume as an addition of cement weight with super plasticizers .A decrease in the compressive strength was noted in the concrete mixtures including 20%, CKD (as a replacement of cement weight).A similar trend was noted in the split tensile strength and the increase in split tensile strength was less pronounced than that in compressive strength.A similar trend was noted in the flexural strength percent increased when CKD was used in concrete mixtures.The using of silica fume enhanced workability, compressive strength, split tensile strength and flexural strength of the concrete for the types of cement.The ordinary Portland cement concrete mixtures including CKD had almost the same behaviors.
