摘要：An attempt was made to study the application of natural polymers for mitigating thecorrosion of reinforcement bars in simulated pore solution. Natural polymers like iota-Carrageenan(i-Carr), Pectin(Pec) and Dextrin(Dex) was used as inhibitors to mitigatethe rebar corrosion. Corrosion monitoring was done by implementing electrochemicaltechniques like impedance spectroscopy and polarization studies. Rct values increasedwith increase in concentration of the inhibitors. Polarization curves implemented theanodic nature of inhibitors. Adsorption of inhibitors was found to fit well withLangmuir adsorption isotherm model. Influence of Cl- ions and a detailed mechanismof their intrusion was also discussed.
