Macro synthetic polymer fibres have the potential to improve the post-cracking properties of hardened concrete. Their use as an alternative to nominal bar or fabric reinforcement is a relatively recent development. This Report is intended for designers, clients and users who are familiar with conventional reinforcement but who may have little experience of the use of fibres. It reviews the current range of applications, including sprayed concrete, external paving and precast units, and gives guidance on aspects such as quality control. Where possible, the design methods being used have been outlined, although in many cases the approaches are still being developed.
