Cortec MCI-2005 ready mix concrete corrosion inhibitor


MCI-2005 is a water-based, organic, corrosion inhibiting admixture for protection of metallic reinforcement in concrete structures.

When incorporated into concrete, MCI-2005 forms a protective, monomolecular layer on embedded metals that inhibits corrosion. In new construction, this is quantified by an increase in critical chloride threshold and subsequent reduction in corrosion rates when corrosion does initiate.

When used with repair mortars and grouts, MCI-2005 not only protects rebar within the patch, it is able to migrate into undisturbed concrete adjacent to the repair, to protect reinforcement already in place.

MCI-2005 has been awarded t h e USA BioPreferred designation (
