  • Active steel repassivator for corroded steel in chloride contaminated reinforced concrete structures
    Patent number: 7041330
    Abstract: An active steel repassivator for the rehabilitation of chloride contaminated reinforced concrete structures and a method for the application of same is disclosed. The active steel repassivator is comprised of a continuous phase, a distributed phase, and/or an aqueous solution of an amine. The continuous phase, also known as the carrier phase, is selected from organic strong volatile bases, salts of weak volatile acids and a non-ionic surfactant. The distributed phase includes an anion containing vanadium in the +4 or +5 state of oxidation. The aqueous solution of the amine acts as a co-inhibitor in the composition.
    Type: Grant
    Filed: May 3, 2004
    Date of Patent: May 9, 2006
    Assignee: Tomahawk, Inc.

  • Corrosion inhibiting admixture for concrete
    Patent number: 6340438
    Abstract: A corrosion inhibiting admixture for concrete is disclosed comprising a combination of organic (amines) and inorganic (nitrites) fractions that provide a synergistic effect when present at a specific ratio. Such a synergistic effect occurs when the amine:nitrite ratio (% by weight) is between 1.5 to 2.5 resulting in the admixture providing excellent corrosion inhibiting capabilities.
