Abstract: Corrosion of embedded steel is a leading cause of deterioration in reinforced concrete structures. While concrete mix designs have become more durable, the possibility of cracking due to shrinkage, movement, or other forces is a consideration when designing for long service life. In addition, preserving integrity and extending the useful service life of existing structures is of paramount importance. Migrating, organic corrosion inhibitors have been used for more than 30 years in construction applications as an economical method of corrosion mitigation. Migrating corrosion inhibitors, based on organic amines have become available with the claimed advantage that, as well as being capable of application as admixtures, they may be applied as remedial agents to the surface of the concrete. This paper will give details on the chemistry of organic corrosion inhibitors, test methods used to assess the efficacy of migrating corrosion inhibitors in concrete and their performance in new construction, repair and specialty applications.
