Cement kiln dust (CKD) is the primary by-product generated during the manufacture of Portland cement clinker. The relatively high alkaline content of CKD is the predominant factor preventing its recycling in cement manufacturing. However, depending on its chemical composition and the water-soluble compounds, CKD can provide the environment necessary to activate slag blended cements. The aim of the present work is to address the key technical issues pertaining to utilization of CKD as an activator for hydraulic slags to create cementitious binders. A study of the effects of the influencing factors in terms of soluble alkali content, particle size, and free lime content was undertaken. Binary blends containing slag and CKDs from different sources were characterized and compared in terms of the rates of heat evolution and strength development, and time of initial setting. The results to be presented will reveal the distinction in the significance of these different parameters.
