Strengths of Cement Kiln Dust Concrete
Publication: Journal of Materials in Civil Engineering
Volume 14, Issue 6
Abstract
This technical note presents the results of compressive, split tensile, and flexural strengths of concrete containing cement kiln dust (CKD) as a replacement for ordinary portland cement (OPC). The replacement levels considered for the study were 20, 40, 60, and 80%. Plain concrete with no CKD was also produced for reference purposes. From the results of the work, it was observed that there was generally a decrease in strength of CKD concrete compared to the reference concrete. However, it was noted that the percentage reduction in strength was minimal when up to 20% of OPC was replaced by CKD in the concrete. The results of the study also confirmed the previous report that the setting time of cement paste increases when CKD is used as a replacement for cement.
