In addition, these concretes must also have homogeneous properties and no segregation. For technical, economical and environmental reasons, cementitious materials (SCMs) are substituted for cement. This study investigates the rheological properties, the compressive strength and durability of self-compacting concrete (SCC) containing slag and blended cement CEMII/A-L 42.5, containing 10% limestone. Slag with a fineness of 3500 cm²/g has been used at different percentages (0%, 10%, 15%, 20%, 25% and 30%) as partial cement replacement. Cement content, water to binder ratio of 0.4, gravel to sand ratio of 1.0 and superplasticizer content of 1.8% (by weight of cement) were kept constant in the all SCC mixtures. The results showed that the incorporation of 25% of slag gives the most favorable effect on the rheological characteristics of SCC which means best deformability, passing ability and good resistance to segregation. At the age of 28 days, there was a decrease in compressive strength with the increase of slag content in SCC. However, a slight increase was observed in water permeability and water capillary absorption for SCC containing 25% of slag compared to SCC control.
