Abstract:  Fiber Reinforced Self Compacting Concrete (FRSCC) is a type of concrete that combines the benefits of Self Compacting Concrete (SCC) with the added strength and durability of Fiber Reinforcement. FRSCC is designed as highly workable, having easy flow and able to fill all voids in the mould or formwork without applying external compaction. Durability is defined as the ability of a material to withstand the effects of weathering, chemical attack, and other environmental factors without significant deterioration over time. FRSCC has been shown to exhibit excellent durability due to its high density, low porosity, and resistance to cracking. The fiber reinforcement provides additional toughness and ductility, which helps to prevent cracking and improve durability. In this study, M35 grade of FRSCC is designed by adding hybrid steel fibers. The effect on mechanical properties and durability of FRSCC is checked with different hybrid steel fibers and with different proportion of fibers. It is found that, steel hybrid Fiber Reinforced Self Compacting Concrete is a promising material with excellent mechanical properties and durability. Its use in construction can lead to improved structural performance, increased safety and reduction in maintenance costs.
