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
