Laboratory and field evaluations are ongoing on several commercially available corrosion inhibiting admixtures for concrete. The study, presently in its tenth year focuses on long-term performance in partially submerged coastal marine applications. The study includes laboratory and field evaluations to determine the ability of the inhibitors to remain stable over long periods of time, determinations of long-term effectiveness of corrosion inhibiting capabilities and a tentative quantitative assessment of durability improvements and possible negative side effects.
