Behavior of Steel Fiber Reinforced Concrete for M-25 Grade

It is now well established that one of the important properties of steel fibre reinforced concrete (SFRC) is its superior resistance to cracking and crack propagation. As a result of this ability to arrest cracks, fibre composites possess increased extensibility and tensile strength, both at first crack and at ultimate, particular under flexural loading; and the fibres are able to hold the matrix together even after extensive cracking. The net result of all these is to impart to the fibre composite pronounced post – cracking ductility which is unheard of in ordinary concrete.

In this paper, the mechanic properties i.e. Compressive, Flexural and split tensile strength of SFRC are discussed.
