       Notes - general: Abstract: A range of factors relevant to the
                        performance of epoxy coated reinforcement were
                        examined in laborartory and eposure trials -
                        coatingthichness measurement and variability, bar to
                        concrete bond strength, coating adhension and
                        corrosion resistance.  Results showed that coating
                        thickness varied but was not signification reduced
                        over ribs and that gauges with small heads were needed
                        to carry out measurements.  No loss in bond strength
                        was detected through the use of epoxy coated
                        reinforcement.  coating adhesion was reduced at bends
                        but loss in adhesion was not a necessary prerequisite
                        for initiation of corrosion.  In exposure trials
                        underfilm corrosion was detected on epoxy coated
                        reinforcement but it was much less intense than
                        corrosion on uncoated bar during the two year exposure
                        period.  Galvanic macroell corrosion currents were
                        significantly reduced by the presence of the epoxy
                        coating.
