Corrosion will reduce the cross-sectional area of strands and deteriorate the mechanical property of prestressing strands. In this chapter, nineteen corroded strands are obtained through controlling stress level, corrosion time, and chloride ion concentration under artificial climate conditions. Then, the size and geometry of corrosion pits are measured, and its probability distribution is investigated. Furthermore, static tensile tests are carried out to study the mechanical property of prestressing strands after corrosion. Following this, a constitutive model of corroded prestressing strand is proposed.
