MCI®-2005 NS (normal set) is a water-based, organic, corrosion inhibiting admixture for protection of metallic reinforcement in concrete structures. When incorporated into concrete, MCI®-2005 NS forms a protective, monomolecular 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. When used with repair mortars and grouts, MCI®-2005 NS not only protects rebar within the patch, it is able to migrate into undisturbed concrete adjacent to the repair, to protect reinforcement already in place.
How It Works
MCI®-2005 NS is an organic corrosion inhibitor and is considered ambiodic (mixed),
meaning it protects both anodic and cathodic areas within a corrosion cell. MCI®-2005 NS contains a blend of amine salts of carboxylic acids which form a protective layer on embedded reinforcement delaying the onset of corrosion as well as reducing existing corrosion rates.
MCI®-2005 NS is effective at enhancing the durability and extending the service life
of concrete structures exposed to corrosive environments (carbonation, chlorides,
and atmospheric attack).
Where to Use
• Reinforced concrete including precast, pre-stressed, and post-tensioned structures • Corrosive environments including exposure to deicing salts, saline groundwater, airborne chlorides, and carbonation • Marine and coastal structures, highways and bridges, parking decks, balconies,
pools, concrete tanks, pilings, substructures, piers, pillars, pipes, and utility poles
• Biobased (27%) • Earns credit towards LEED certification • Lower toxicity and environmental impact than traditional corrosion inhibiting admixtures such as calcium nitrite • Low dosage rate with minimal effect on concrete properties (i.e. workability, strength development, air entrainment, etc.) • Ability to migrate through porous substrates (concrete, masonry, limestone, etc.) by capillary action, vapor diffusion and ionic attraction • Meets all requirements of ASTM C1582 • Certified to meet ANSI/NSF Standard 61 for use on structures holding potable water • Field and lab tested worldwide • Complies with CSA S413, Section C1.2, for corrosion inhibiting • Single dosage rate independent of expected exposure to chlorides (1.5 pts/yd3) •Made in USA
