scope:

This standard presents corrosion control guidelines that are applicable to existing atmospherically exposed structures made of conventionally reinforced concrete. These guidelines may be used to develop specifications involving repair and rehabilitation of steel-reinforced concrete structures. These guidelines should be used primarily when repair or rehabilitation is being imple- mented because of deterioration resulting from the corrosion of steel reinforcement.

This standard describes various approaches that may be taken with respect to corrosion control of existing structures. The flow chart in Figure 1 delineates the repair or rehabilitation strategy covered in this standard. Because of the complexity of corrosion problems on individual structures, advice from a Professional Engineer or a Corrosion Specialist, whose professional qualifi- cations include suitable experience in corrosion control of reinforced concrete structures, should be sought before proceeding with repair and rehabilitation programs.

This standard does not cover pre-tensioned and post-tensioned reinforced concrete.

Appendix A contains a glossary of many terms used in this standard.
