Mini MCI® Grenades consist of Migrating Corrosion Inhibitors (MCI®) packaged in water-soluble PVA bags. Mini MCI® Grenades are very convenient to use. 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. The MCIs protect reinforcing steel, galvanized steel, and other metals embedded in concrete from corrosion induced by carbonation, chloride, and atmospheric attack. When incorporated into the concrete mix the MCIs form a corrosion inhibiting protective layer on metals. When used with repair mortars and grouts, MCIs will migrate toward the rebars providing effective corrosion protection.
