Product Description
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 MCI 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 theMCI®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®

form a corrosion inhibiting protective layer on metals. When used with repair mortars and grouts,MCI®will migrate toward the rebars 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 concrete mix
• Required dosage is not affected by chloride concentration-One Mini Grenade (10 g) per 0.5       ft3/ 0.015 m3
• 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
• Cortec logo on each bag ensures MCI® inhibitor is inside Mini MCI Grenades®

Typical Application
Mini 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
