| 摘要： | This is a feasibility study of the injection of synergistic corrosion inhibitors for protection of concrete bridge components. The research developed electrically injectable corrosion inhibitors that provide 78-85% corrosion protection for the rebars. This technology can be further improved to provide 90-100% corrosion protection for rebar steel. Inhibitor injection requires approximately 1,000 times higher current densities than those used for cathodic protection. An advantage of this technique is that the equipment required is similar to that used in cathodic protection, and hence, is familiar to highway bridge engineers. However, unlike cathodic protection which requires a permanent installation, protection using inhibitor injection requires only a temporary installation for a few days. The experimental details are described, and the details are given of the electromigration studies, and the inhibitor studies. The results are presented and discussed. |
