MCI®-2006 NS (normal set) is a powder concrete admixture that protects steel reinforcing, carbon steel, galvanized steel and other metals embedded in concrete from corrosion induced by carbonation, chloride and atmospheric attack without changing the set time of most concrete mixes. MCI®-2006 NS protects using a time proven migratory corrosion inhibitor function. In addition, it contains a proven contact inhibitor. When incorporated into the concrete mix, Migrating Corrosion Inhibitors (MCI®) seek out and form a corrosion inhibiting, protective layer on metals. When used with repair mortars and grouts, MCI®-2006 NS will migrate to undisturbed concrete providing effective corrosion protection to rebar already in place.
