“…5b) also the behavior of the specimen take a shift from resistive (high frequency) to capacitive side (low frequency) at 1 day of exposure duration. The observed capacitive behavior suggests the presence of homogeneous protective layer on the rebar (Jamil et al 2004;Ford et al 1998).…”

“…Observed higher value of R 2 suggests that inhibitor reinforced the passive film on the rebar probably by surface adsorption (Criado et al 2012). Jamil et al (2004) also suggested that amino alcohol based inhibitor are able to displace hydrated layer of the iron oxides/ hydroxides surface film in order to create more favorable anchorage sites for the formation of protective inhibitor layer. However, in this present study the transport and protection mechanism of the inhibitors were not studied.…”

“…Apart from admixed inhibitors, surface applied inhibitors also gained popularity during the past 15 years. Wombacher et al 2004;Malik et al 2004;Holloway et al 2004;Soylev et al 2007 andJamil et al 2004 investigated the effectiveness of surface applied inhibitors in chloride induced corrosion. Most of the previous studies investigating the performance of surface applied organic inhibitors focused on chloride induced corrosion.…”

In this paper, electrochemical impedance spectroscopy was used as non destructive technique (NDT) for studying the carbonation behavior of the concrete sample treated with migratory type of organic corrosion inhibitors. Concrete carbonation was achieved in carbonation chamber by maintaining 5% CO 2 by volume, 60-70% relative humidity and 30 ± 2°C temperature for 90 days. The experimental results show that with progressive carbonation, porosity of the concrete reduces and results in denser microstructure. The concrete surface treated with corrosion inhibitor C.I. 1 (amine -ether based) and C.I. 2 (2-aminobenzoic acid) shows the behaviour different form the control sample at the end of exposure conditions. Impedance results indicate that carbonation depth can be predicted by analyzing the high frequency arc of Nyquist plot. Also, both of the tested inhibitors were able to form a passive layer around the rebar surface and their efficiencies improved with time.

“…1 Cross-sectional details of (a) bare steel specimen used for synthetic solution (b) rebar embedded in concrete specimens. sion, organic-based corrosion inhibitors are found to be effective (Heiyantuduwa et al 2006;Monticelli et al 2011;Nmai 2004;Montemor et al 2002;Jamil et al 2004). Therefore, organic compounds such as ethanolamine, amine-ether based corrosion inhibitor, aminoalcohol based corrosion inhibitor, Anthranilic acid were chosen for present research.…”

The carbon steel electrodes were first treated by immersion in 0.1 M phenyl phosphonic acid (C 6 H 5 P(O)(OH) 2, PPA) solution during 24 or 72 hours, then they were transferred into the corrosion test solution representing interstice pore electrolyte polluted by seawater:sat. Ca(OH) 2 + 0.5M NaCl) to evaluate the protective effectiveness of the pre-treatment. The investigation was performed essentially by polarization curves and electrochemical impedance measurements with rotating disc electrode. Very high protective effect was observed with steel pre-treated during 72 hours with stationary electrode. From polarization and electrochemical impedance spectroscopy experiments, the protective efficiency was found to be in the 90-99% range for 72 hour pre-treatment. This protective property remains effective even one month immersion. EDS analysis showed the presence of the phosphorus on the steel surface, probably due to the presence of iron-PPA complex.
