Steel fibre reinforcement is widely used as the main and unique reinforcing for industrial concrete floor slabs,
shotcrete and prefabricated concrete products. It is also considered for structural purposes in the
reinforcement of slabs on piles, tunnel segments, concrete cellars, foundation slabs and shear reinforcement
in prestressed elements. Ensuring the quality and performance of the steel fibres and ultimately the SFRC is
critical and the challenge faced by engineers involved in designing these projects is to unambiguously
specify the performance required by the SFRC so as to achieve in the finished structure the performance
that was assumed in design.
