Abstract

Electrochemical potential monitoring experiments have been · fc:' performed on the mild steel rebars embedded in concrete !· admixed with different inhibitors and sodium chloride salt and e~posed to sea water environment. The electrode potential of j ·:; the reinforcing s eel was monitored during the experiments and this paper r ports the observed electrochemical . response. The effects of admixed inhibitors on the . compressive strengths of the used reinforced concrete are also reported. The inhibitors were added to the concrete to protect the steel from corrosion. Varied measures of protection were provided by the different inhibitors. Although the inhibitor must not be detrimental to concrete properties, loss of compressive strengths was recorded for the concrete admixed with formaldehyde. Sodium nitrite did not give any effect, and potassium chromatic gave an increase in compressive strength of the concrete exposed to seawater. the overall protective effect of the inhibitors was minimal.
