Hycrete X1000: reduces the permeability of concrete, up to seven times better than control concrete as measured under the BSI 1881-122 test. There is a natural reluctance to their use in concrete because they cannot be changed if found to be ineffective, replenished if found to be consumed, or removed if . Corrosion is the leading cause of concrete relapse, and corrosion inhibitors are the key to metal defense. MCI-2005 - Organic amine carboxylate-based migrating corrosion inhibitor for enhancing the durabiity of reinforced concrete structures. The inhibitors for concrete are classified as an anodic, cathodic, and mixed type of inhibitors based on the mode of action. RUST-X CCI 4207 powder is an excellent corrosion inhibitor which can be mixed with the concrete during the construction. The effectiveness of a corrosion inhibitor depends on fluid composition, quantity of water, and flow regime. Migratory Corrosion Inhibiting Liquid for In Service Infrastructure. Corrosion inhibitors provide the right performance in concrete for mitigating deterioration caused by the aggressive chloride exposure conditions. The life expectancy of metals, steel and rebar can also be increased through reducing chloride permeability, creating safer and stronger structures. Since Corrosion Inhibitors normally contain 20.9% Nitrite, if, for example, 5.4 gallons of CI were added, the weight of only the nitrite portion per cubic yard would be 12.2 lbs.
