NEW TRENDS IN MIGRATING CORROSION INHIBITOR TECHNOLOGY FOR CORROSION PROTECTION OF EMBEDDED STEEL REINFORCEMENT

摘要

Lower whole-life costs are achieved by choosing effective protection systems during the design stage of an engineering structure. A "belt and braces" corrosion protection system will often include Migratory Corrosion Inhibitors (MCI~®) and Vapor Phase Corrosion Inhibitors (VpCI~®), galvanic protection and life time monitoring of the corrosion process. This paper presents novel MCI (cementitious) and VpCI (epoxy, polyurethane, acrylic) technologies and a new galvanic coating derived from NASA research. The competing mechanisms of corrosion protection are supported by case histories of successful worldwide applications
