The wide use of self-compacting concrete (SCC) in the precast industry versus its moderate use in the ready-mixed concrete industry, has led to the development of products within the upper-middle performance range, leaving gaps unfilled in some applications where low or medium strength is required. The aim of this paper is to demonstrate, theoretically and practically, the feasibility of developing SCC in the range of medium strength. In this study, cement kiln dust (CKD) was used as a local filler, and six mixtures with different percentages of cement replacement by CKD were investigated. Properties at fresh and hardened state were studied. The use of high percentages of CKD and different combinations of water/fines ratio allows economizing on the use of the admixture and the amount of cement required, obtaining SCC of medium strength and lower production costs.
