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 Grenades® per 1 cubic yard or one 650g
Metric MCI Grenades® 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 MCI®s 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 MCI®s form a corrosion inhibiting protective layer on metals. When used
with repair mortars and grouts, MCI®s will migrate toward the rebar providing
effective corrosion protection.
•Offers engineers, owners, contractors, DOTs, and government agencies a time proven corrosion inhibiting technology that will extend the life of reinforced concrete structures
•Protects against the harmful effects of corrosion even in the densest concrete
•Does not affect the air entrainment, compressive strength, or the set time of
•Required dosage is not affected by chloride concentration
•One MCI Grenade per 1 cubic yard of concrete mix or one Metric MCI Grenade
per 1 cu meter
•Does not contain calcium nitrite
•Non-flammable and environmentally friendly
•Lab and field tested
•Concentrated for cost effectiveness on all projects
•Will migrate to adjacent areas to protect surrounding metals
MCI Grenades®MCI Grenades are recommended for:
•All reinforced, precast, prestressed, post-tensioned, or marine concrete structures
•Steel-reinforced concrete bridges, highways, and streets exposed to corrosive environments (carbonation, deicing salts, and atmospheric attack)
•Parking decks, ramps, and garages
•Concrete piers, piles, pillars, pipes, and utility poles
•Restoration and repair of all reinforced concrete commercial and civil engineered structures.
