Cortec MCI Mini Grenade Corrosion Inhibitor


MCI Mini Grenades consist of Migrating Corrosion Inhibitors (MCI®) packaged in small, water-soluble PVA bags. Mini MCI Grenades are ideal for repair mortars–one Mini Grenade protects 0.4-0.6 ft3 (0.015 m3). The grenade dissolves easily when in contact with water in the concrete mix. During mixing the bag will completely dissolve and the MCI compounds will begin to disperse into the mix.
