Anti-corrosion Performance of a New Corrosion Inhibitor for Rebar

The anti-corrosion performance of a new rebar inhibitor containing amino group and carboxylic group was evaluated by means of hardened mortar test and half cell potential method. The adsorption of corrosion inhibitor on rebar in concrete was analyzed. The results show that the corrosion inhibitor could delay the corrosion and reduce the corrosion rate of the rebar.
