MCI® Grenades consist of powder Migrating Corrosion Inhibitors (MCI®) packaged in water-soluble PVA bags. MCI® Grenades are convenient to use and are available in three sizes for easy dosing.
When incorporated into concrete, MCI® Grenades form a protective, molecular layer on embedded metals that inhibits corrosion. In new construction, this is quantified by an increase in critical chloride threshold and subsequent reduction in corrosion rates when corrosion does initiate. In repair, MCI® Grenades not only reduce corrosion on metals within the patch area, but are also able to migrate into undisturbed concrete adjacent to the repair to protect reinforcement already in place near the patch.
Package: MCI® Grenades are available in 1.1 lb (500 g) bags (40 per carton) and 5 lb (2.3 kg) bags (10 per carton). MCI® Metric Grenades are available in 1.43 lb (650 g) bags (32 per carton). Please see MCI® Mini Grenades if you need sizes for bags of repair mortar. To ensure best product performance, store in original packaging, indoors, and out of direct sunlight at 40-100 °F (4-38 °C).
