Abstract:

The integrity and corrosion performance of epoxy-coated reinforcement in aggressive environments was investigated through a series of experimental studies, including: a) use of holiday detection for assessing damage to coating; b) hot water immersion and knife testing for assessment of coating adhesion; c) assessment of materials and procedures for repairing coating damage; d) evaluation of degree of mechanical damage caused during concrete placement when using metal head or rubber head vibrators; e) accelerated corrosion of coated bars embedded in macrocell and beam specimens placed in a corrosive environment for more than four years. The effects of coating condition and amount of damage, repaired vs. unrepaired damage, bar fabrication, and concrete cracking were studied. The findings are summarized and guidelines for quality control, design, and construction practice are included.
