Material extends life of  concrete structures

MCI-2008 ViaCorr is an organic-based concrete admixture in powder form which combines Cortec’s Migratory Corrosion Inhibition Technology with a polycarboxylate based, superplastisizing, viscosity modifier. MCI-2008 ViaCorr is said to offer engineers, owners, contractors, DOTs, and government agencies exclusive corrosion inhibiting technology that will extend the life of all reinforced concrete structures and reduce construction time as well as equipment costs and manpower for placing and compacting.

The company is said to recommend the material as an additive for selfleveling concrete used in many areas including all reinforced, precast, prestressed, and post tensioned concrete structures; steel-reinforced concrete bridges, highways, roads, and buildings exposed to corrosive environments (carbonation, deicing salts, and atmospheric attack); reinforced marine concrete structures and concrete piers, piles, pillars, pipes, utility poles and architectural concrete.

MCI-2008 ViaCorr protects carbon steel, galvanized steel and other metals embedded in concrete from corrosion induced by carbonation, chloride and atmospheric attack. When incorporated into the concrete mix, MCI®-2008 ViaCorr seeks out and forms a corrosion inhibiting protective layer on metals. When used with repair mortars and grouts, MCI - 2008ViaCorr will migrate to undisturbed concrete, providing effective corrosion protection to rebar already in place.

The chemical structure of MCI admixtures is such that they do not decompose over an extended period of time, making them effective for periods in excess of 34 years. This effectiveness has been proven in two long-term independent test programs: The Strategic Highway Research Program (SHRP) and Cracked Beam studies based on ASTM G 109.
