Cortec Corp., a global provider of corrosion protection technology, has introduced a concrete admixture designed to inhibit corrosion in rebar.

MCI 2005 is an organic, water-based admixture that protects carbon steel, galvanized steel and other metals embedded in concrete from corrosion induced by carbonation, chloride, atmospheric attack and other corrosive contaminants.

Protective Molecular Layer

MCI 2005 can migrate “a considerable distance” through concrete, forming a corrosion-inhibiting protective layer on metals, according to Cortec. The product maintains structural integrity and extends the service life of concrete structures while being environmentally friendly, the manufacturer says.

MCI 2005 is ambiodic (mixed), meaning that it protects both anodic and cathodic areas within a corrosion cell. It contains a blend of aminoalcohols and salts of carboxylic acids, which protects embedded reinforcement from corrosion even in the densest concrete, according to Cortec.

Features and Applications

MCI 2005 is bio-based (produced from sugar beets), nonflammable, non-toxic, nitrite-free and will not adversely affect physical properties of the concrete mix, the manufacturer says.

Lab- and field-tested worldwide, the admixture conforms to ASTM G109 (Standard Test Method for Determining Effects of Chemical Admixtures on Corrosion of Embedded Steel Reinforcement in Concrete Exposed to Chloride Environments) and has been approved to meet NSF Standard 61 for potable water applications.

Cortec says MCI 2005 has been used in numerous applications worldwide, including a new drinking-water reservoir in Ecuador and the Burj Khalifa Tower, the world’s tallest building.
