The inhibitor will migrate a considerable distance through the concrete to deposit itself on the internal bars. A small quantity of the inhibitor can be added to the concrete by the mixer. The dosage is not determined by the chloride level in the concrete. The inhibitor attaches to the steel reinforcement forming a thin, protective coating of MCI molecules. Once a concrete structure is built, it's impossible to coat the reinforcing steel with fusion-bonded epoxy to protect it from corrosion.
Cathodic protection is ineffective unless the steel reinforcement is electrically continuous.
Cortec MCI, however, can be easily added to concrete for rehabilitation and will not delay construction or increase construction costs other than the small cost of the material. Unlike standard inorganic inhibitors, Cortec MCI's do not have to come in contact with the reinforcing steel upon application in order to seek out the steel and protect it. When specified in new construction, Cortec's MCI line of concrete admixtures offers reinforcing steel superior corrosion protection against chloride attack. The effects of MCI corrosion protection do not compromise any of the physical properties of concrete at the recommended dosages.
