Corrosion protection system for construction and rehabilitation of reinforced concrete bridges
Corrosion is an inescapable process, since all processed construction materials eventually revert back to their natural form. The FHWA (Federal Highway Administration) has made much progress in the area of new bridge construction for the last 25 years. The corrosion protection systems that are in use today are performing satisfactorily. More needs to be done in developing corrosion resistant reinforcements and other corrosion protection systems such as corrosion inhibitors and more durable concrete mix designs. Since all materials will eventually degrade, in the future we have to find ways to rehabilitate the so called corrosion resistant bridges of today with improved, cost effective methods and technologies. At present, in the USA, there are a significant number of bridges which contain black steel rebars and thus will need attention in the future. The present challenge is to make cathodic protection, electrochemical chloride removal, and other processes, cost effective for bridge owners to use. Corrosion engineers and scientists will always play major roles in the development of corrosion resistant materials for more durable bridges and in finding methodologies for extending the lives of existing bridges.
