NEW PERSPECTIVES IN CORROSION PROTECTION FROM MCI®
What is Cortec MCI Technology?
Cortec Corporation’s patented MCI (Migrating Corrosion Inhibitor) Technology protects reinforcing metal in concrete from corrosion. Often, corroding rebar in deteriorating concrete is the cause of costly repairs, financial losses, injuries, and even deaths, but Cortec has the corrosion solution. MCI greatly extends the service life of new and existing structures by proactively delaying the onset of corrosion and keeping rates low after initiation. Cortec MCI products maintain structural integrity, rehabilitate vulnerable structures, and alleviate environmental concerns.
How Does MCI Technology Work?
MCIs are based on amine technology (amine alcohols and amine carboxylates). They are classified as mixed inhibitors, meaning they affect both anodic and cathodic portions of a corrosion cell. MCI® is applied in many forms including as a concrete admixture or a topical treatment. It moves as a liquid through the concrete matrix via capillary action and migrates in a vapor phase throughout the concrete pore structure. When MCI® comes in contact with embedded metals, it has an ionic attraction to it and forms a protective molecular layer. This film prevents corrosive elements from further reacting with the reinforcement and also reduces existing corrosion rates, greatly extending concrete service life.
Durability and Sustainable Construction
Sustainable construction has become a goal for owners across the globe. While much attention has gone to reducing cement use and minimizing power and water consumption, an often overlooked aspect is the durability and service life of the final structure. However, this is undoubtedly one of the key parameters influencing structural sustainability. By using MCI in severely corrosive environments, structures will have a stronger resistance to corrosion and therefore possess greater durability. Increased durability will mean fewer repairs, greater structural integrity, and a longer service life, all leading to greater sustainability. MCI is made from a renewable raw material, enabling users to earn certain LEED credits. It is an excellent addition to building projects around the world seeking to meet sustainability standards such as the Estidama Pearl Rating System and BREEAM.
