Abstract :In the paper, Feasibility of preparing self-compacting concrete (SCC) was evaluated. Six mixes are designed to replace part of the cement with cement kiln dust (CKD). The first mix without replacement is the control mixt through which the rest of the mixtures are compared. As for the remaining five mixtures, part of the cement was replaced with CKD, and the replacement ratios are (2.5, 5, 7.5, 10, 12.5) % sequentially. Where the ratio of water to cement was constant is 0.3 in all mixes SCC. Then the viscosity, flow ability, passing ability and segregation properties of all mixes were examined, and then some mechanical properties (compressive resistance, dry density, ability of water absorption ) were examined for all mixes. The results indicate a decrease in the workability (passing ability, flow ability, and segregation) and mechanical properties (compressive strength and density) and also led to an increase in the viscosity of T500, as well as an increase in the water absorption ability of SCC. In general, the mechanical properties of some mixes are acceptable compared to the reference mix, especially when it is replaced by a few percentages
Keywords : Self compacting concrete, Cement kilt dust, Workability, Replacement, segregation
