The materials used in the high-performance concrete leads to extreme brittleness, to overcome these different fibres are introduced in the concrete to improve its tensile strength and ductility. Slurry Infiltrated Fibrous Concrete (SIFCON) is one type of special concrete in which steel fibres are placed in an effective way for its interlocking system for concrete toughness. In this study SIFCON with two different steel fibres hooked end and crimped end were used in different volume ratios of 5%, 6%, 7%, 8% and 9% separately to investigate its mechanical properties. The further investigation was carried out by replacing Ground Granulated Blast Slag (GGBS) as binder replacement with optimum fibre ratio. From the results it is concluded that hooked end fibre shows an increasing performance when compared to crimped end fibre. Similarly, the strength increment is observed when GGBS is used as binder replacement at 40%. Microstructural analysis with the help of SEM and XRD are performed, and the results indicated that a similar hydration phase with increased rate is observed in SIFCON when compared to conventional concrete.
