MCI-2005 Gel Corrosion Inhibitor Construction worker drilling into concrete road

MCI-2005 Gel

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 the USA Bio Preferred™ designation (
