TECHNOLOGY THAT EXTENDS THE SERVICE LIFE OF CONCRETE STRUCTURES Concrete is one of earth’s most widely used materials and will continue to be so as the population grows. Aside from its structural capacity, concrete’s durability is a key property that makes it preferred for construction. However, concrete durability is affected by environmental conditions, including physical and/or chemical attack. A dominant form of concrete failure seen in most parts of the world is due to steel reinforcement corrosion. How Does MCI® Technology Work? MCIs are based on amine technology. 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 concrete admixtures and topical treatments. 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 reduces existing corrosion rates, greatly extending concrete service life.
