MCI-2007 Liquid and MCI-2007 Powder are water reducing admixtures with Cortec’s exclusive Migratory Corrosion Inhibitor technology. MCI- 2007 Liquid is melamine based and meets the Type G admixture requirements of ASTM C494. MCI-2007 Powder is polycarboxylate based and meets the Type F admixtures requirements of ASTM C494. They reduce mixing water by 20- 30% depending on cement type and protect reinforcing such as carbon steel, galvanized steel and other metals embedded in concrete from corrosion induced by carbonation, chloride and atmospheric attack. They are recommended for use in all concretes, especially reinforced, prestressed and post-tensioned concrete. When incorporated into the concrete mix, MCI- 2007 Liquid and MCI-2007 Powder seek out and form a corrosion inhibiting protective layer on metals. When used with repair mortars and grouts, MCI-2007 Liquid and MCI-2007 Powder will migrate to undisturbed concrete, providing effective corrosion protection to rebar already in place.
