Bond behavior between strand and concrete plays a decisive role in sustaining the properties of prestressed concrete structures. This chapter mainly discusses the bond behavior between corroded strand and concrete. First, the effects of corrosion-induced crack on the bond between strand and concrete are studied based on the pull-out test; the confinement role of stirrups on the deterioration of bond behavior affected by concrete cracking is addressed. Next, the bond behavior of corroded strand in pretensioned concrete structures is investigated by the bending test; the effects of strand corrosion on force–slip curves, bond strength, and failure mode are discussed.
