Abstract
Description
Electrochemical pote111ial ·monitoring experiments have been
performed On the mild steel rebars embedded in concrete admixed with two different inhibitors in variable concentrations and sodium chloride salt, and ~posed to 0.5M dilute sulphuric acid and seawater environments. The electrode potential of the reinforcing steel rebar in the concrete was monitored during the experiments
and this paper reports the observed electrochemical response.
Neither the various concentrations of sodium nitric inhibitor no that of the sodium benzoate alone could provide any effective protection to the embedded steel. The combination of the · two inhibitors; however, gave synergistic protective effect at some concentrations in the two different test media.
