Abstract:Because of the shortage of aggregate, the reinforced concrete -containing sea sand and/or sea water can probably be used for marine structures. These marine structures may experience corrosion problems due to salt attack that can result in early deterioration. Therefore, such structures should be protected against corrosion damage induced by chloride ion to extend the service life. This study was focused on a basic counter-plan against concrete corrosion related to marine infrastructures, especially the evaluation of effects of various corrosion inhibitors with different cover thicknesses. Several electrochemical/corrosion test techniques, i.e. half -cell potential, linear & cyclic polarization behaviors & autopsy inspection, were included. Based on this long-term(7 years) study, it was concluded that a chloride ion accelerated reinforcement corrosion seriously, however, a increase of cover thickness and adoption of some inhibitors could provide positive effects against the chloride-induced corrosion. In addition, it was recognized that the electrochemical corrosion tests generally agreed with those of visual autopsy examinations in these long-term experiments.
