Effect of cement kiln dust (CKD) on mortar and concrete ...

Jul 01, 2003  Replacement of cement by CKD will lead to less cement content and, therefore, less strength. However, small amounts of replacements of up to 5% do not seem to have an appreciable adverse effect on strength, especially at low water-to-binder ratios. At 5 and 10% CKD substitution for Portland cement, the reductions in the 28-day compressive ...

Cement Replacement - an overview ScienceDirect Topics

The influence of 15% CKD– cement replacement on the electrical resistivity of concrete mixes was observed by Maslehuddin et al. (2008) and Konsta-Gdoutos et al. (2001). Both studies concluded that incorporation of CKD decreased the electrical resistivity of the resulting concrete due to the increase of free chloride ions.
