Durability study of hot-dip galvanised reinforcement bars in carbonated and chloride-contaminated concrete

Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review


The study presents the work studying the factors influencing on the durability of hot-dip galvanised reinforcement bars. The experimental part of the study consisted of accelerated corrosion tests. The comparison of the measured crack width of concrete with the rate of corrosion values, and also with other measured values such as the corrosion potential, the resistivity of concrete, and the mechanical properties of the steel indicated no correlation irrespective of the duration of the exposure or type of aggressive liquid. The rate of corrosion decreased as a function of exposure time. This phenomenon may have a positive effect on improvement of the service life of reinforced concrete structures. The research result was not dependent on the water-tocement ratio of concrete. Finally, three probable corrosion mechanisms were determined for hot-dip galvanised reinforcement bars in cracked concrete.
