What is the advantages of the Steel fibre-reinforced shotcrete ?

The primary advantages of fibre-reinforced shotcrete are:

• Addition of steel fibers into the concrete improves the crack resistance (or ductility) capacity of the concrete. Traditional rebars are generally used to improve the tensile strength of the concrete in a particular direction, whereas steel fibers are useful for multidirectional reinforcement. This is one of the reasons why steel fiber reinforced (shotcrete form) concrete successfully replaced weldmesh in lining tunnels.
• Less labour is required.
• Less construction time is required.
