In this paper, early results from an on-going project aimed at investigating the influence of fibre reinforcement on corrosion of rebar are presented. Resistivity of mixes containing fibres was reduced when compared with plain concrete while chloride migration seemed to remain unaffected. On the mechanical properties, results showed that while the flexural behaviour was greatly enhanced by addition of fibres up to 0.5% vol., the variation in compressive strength was negligible regardless of the fibre type. Early results from the main experiments indicated a tendency of earlier corrosion initiation with increasing crack width, and that the initiation time was somewhat delayed for the fibre reinforced specimens.
