Scope and Limitations

Because of the concrete damage caused by the corrosion products formed on reinforcing steel, the designer should consider certain corrosion criteria during the design of the structure. Design and construction considerations should be based on good engineering practices to eliminate conditions conducive to corrosion. The guidelines in this standard give the designer several alternative methods of controlling the corrosion of a proposed atmospherically exposed, submerged, or buried reinforced concrete structure.

This standard does not designate specific design practices for the control of corrosion because of the complexity of corrosion mechanisms in individual structures. This standard does not cover areas such as welding of reinforcement for which other professional societies have published pertinent standards. Although many of the statements in this standard are applicable to prestressed concrete structures, this standard does not address this type of reinforcing system.

The standards mentioned here (American Concrete Institute [ACI],⁽¹⁾ ASTM International [ASTM],⁽²⁾ and American Association of State Highway and Transportation Officials [AASHTO]⁽³⁾), have been prepared for applications in the U.S. The international practitioner should refer to local standards, if such are available.

During the design phase of a reinforced concrete structure that could be affected by corrosion, the services of a qualified Professional Engineer or qualified Corrosion Specialist shall be obtained so that proper materials selection and engineering practices for corrosion control are included in the design. Professional qualifications shall include suitable experience in corrosion control of reinforced concrete structures. The provisions of this standard shall be applied under the responsible charge of said Professional Engineer or Corrosion Specialist.
