Abstract: Self compacting concrete achieves compaction by itself without using mechanical vibration techniques. Addition of fibers to SCC results in increased performance mainly in flexure, and also in compressive strength. In this study both the flow and strength properties of single Fiber and blended fiber reinforced self compacting concrete are examined in comparison with control self compacting concrete. crimpled steel fibers having size of 0.45mm diameter x 12.5mm length (aspect ratio 27.7) and 0.45mm diameter x 20 mm length (aspect ratio 44.44) are used in the SCC mix at various percentages by weight of cement i.e. 0%, 2%, 4% and 6%. From the obtained results it can be seen that there is aadverse affect on flow properties. There is a moderate increase in the compressive strength, split tensile strength and considerable increase in the flexural strength of the self compacting concrete using the blended fibers at different percentages i.e. at 2% and 4%, when compared to the single fiber reinforced self compacting concrete.
