Migrating Corrosion Inhibitors Help Protect Concrete Arch Bridge
Cortec announced that its product, MCI 2020, is being used to treat the steel and concrete of Krk Bridge, a reinforced concrete arch bridge connecting the Croatian island of Krk to the mainland and carrying over a million vehicles per year. Investigators discovered that salt accumulates on the surface of the reinforced concrete structure and chlorides penetrate through the protective layer of concrete to attack the reinforcement because of strong winds at the site.
Repairs are continuously carried out in several phases during a 30-year timeframe.
