Abstract: Self-compacting concrete (SCC) is relatively a recent development in the construction world. SCC can flow through dense reinforcement under its own weight without any segregation, bleeding, and vibration. The use of steel fibers is being encouraged to increase mechanical characteristics of SSC. However, adding fibers to fresh concrete results in loss of workability. Steel fibers operate as crack arrestors in concrete and extend the span of structures. In the present study, the mechanical properties of SCC with cement is partially replaced by rice husk ash (RHA) & P500 (ultra-fine fly ash). A total of 5 mixes with 0.3 W/C ratio were cast for 7, 28 and 56 days water curing. The replacement of fibres is considered as 0%, 0.5%, 1%, 1.5%, and 2% by weight of cement. Workability, Compressive, Split Tensile and Flexural strength is studied in this investigation. Superior strength was observed at optimum dosage of steel fibers at 1.5% by weight of cement.
