In terms of corrosion, bond strength is most commonly used in reinforced concrete. It is a measure of the transfer of load between the concrete and reinforcement. Bond strength is influenced by:
Bar geometries
Concrete properties
Amount of confinement around the bar
Surface conditions of the bar
For reinforced concrete , it is necessary to create a suitable bond between steel bars and the surrounding concrete. The bond ensures that there is little or no slip of the steel bars relative to the concrete and the means by which stress is transferred across the steel-concrete. Bond resistance is made up of chemical adhesion, friction and mechanical interlock between the bar and surrounding concrete
