Improving life expectancy of Reinforced Concrete Structures using Migrating Corrosion Inhibitors  

Corrosion is one of the primary concerns in the durability of materials and structures. Research efforts have been made to find a corrosion inhibition process to prolong the life of existing structures and minimize corrosion damages in new structures. Migrating Corrosion Inhibitor technology was developed to protect the embedded steel rebar/concrete structure. In this talk the focus will be on the improving life expectancy of reinforced concrete. Concrete provides excellent protection for embedded steel because Portland cement is very alkaline, forming a passive, protective layer on the steel surface. Concrete is also permeable, and even good-quality concrete can be penetrated by aggressive chemical ions that may initiate steel corrosion. Migrating corrosion inhibitors (MCIs), a blend of amine carboxylates and amino alcohols, show versatility as admixtures, surface treatments (coatings) and in rehabilitation programs.  In this presentation, it will be re-affirmed that the most cost efficiency method is the use migrating corrosion inhibitor admixture to improve durability of reinforced steel concrete structures in aggressive environments.
