Abstract:This report reflects the current understanding of corrosion of prestressing steels in concrete. The report includes chapters that cover the various types of prestressing steel, including some discussion on metallurgical differences. Deterioration mechanisms are discussed, including hydrogen embrittlement and stress-corrosion cracking. Methods to protect prestressing steel against corrosion in new construction are presented, along with a discussion of field performance of prestressed concrete structures. Finally, field evaluation and remediation techniques are presented.
