MCI Grenades consist of Migrating Corrosion Inhibitors (MCI) packaged in water-soluble PVA bags. MCI Grenades are very convenient to use and come in two sizes for easy dosing. One 500g MCI Grenade per 1 cubic yard or one 650g Metric MCI Grenade per 1 cubic meter provides excellent protection to steel reinforcement. MCI Grenades dissolve 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.
