Effect of Steel Fibers on Compressive and Flexural ...

The fibers are capable of Carrying a load across the crack. 2. What is F. R. C? The presence of micro-cracks at the mortar aggregate interface is responsible for the inherent weakness of plain concrete. The weakness can be removed by in inclusion of fibers in the mix. The fiber helps to transfer the loads at the internal micro-cracks.

IMPACT RESISTANCE AND STRENGTH RELIABILITY OF FIBER ...

This proves that the steel fibers act as an effective crack arrestor in case of FRC, when an impact load is encountered. Thus the plain concrete exhibits an early brittle failure when compared to FRC which shows better ductile properties (Swamy and Jojagha, 1982). Figure-2. Impact failure energy of FRC.
