• Abstract:
  In reinforced concrete systems, ensuring that a good bond between the ; concrete and the embedded reinforcing steel is critical to long-term structural ; performance. Without good bond between the two, the system simply cannot ; behave as intended. ; The bond strength of reinforcing bars is a complex interaction between localized ; deformations, chemical adhesion, and other factors. Coating of reinforcing bars, ; although sometimes debated, has been commonly found to be an effective way to ; delay the initiation of corrosion in reinforced concrete systems. ; For many years, the standard practice has been to coat reinforcing steel with ; an epoxy coating, which provides a barrier between the steel and the corrosive ; elements of water, air, and chloride ions
