MCI® Fiber Grenades Powder Admixture

MCI Fiber Grenades consist of both fiber and powders containing Migrating Corrosion Inhibitors packaged in water-soluble PVA bags.

The poly propylene based fibers in MCI Fiber Grenades add mechanical and corrosion inhibiting benefits. Shrinkage cracking decreased 66%, while the residual strength doubled when compared to concrete alone. The MCI Fiber Grenades also add extra long corrosion protection because the MCI is released more slowly. MCI Fiber Grenades provide corrosion protection from atmosphere and chloride attack, as well as from carbonation.

Application: MCI Fiber 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
