NACE SP0187

Abstract

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 methods should be based on good engineering practices to eliminate or reduce conditions conducive to corrosion. The methods in this standard give the designer several alternative methods of controlling the corrosion of atmospherically exposed, submerged, or buried reinforced concrete structures.  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. In addition, the standard does not address the use of non-metallic reinforcement systems.  Several of the standards referenced in this standard (American Concrete Institute [ACI(1)], ASTM International [ASTM(2)]), are applicable internationally, while standards such as those of the American Association of State Highway and Transportation Officials (AASHTO),(3) have been prepared for applications in the United States. The practitioner also should refer to local standards, if available. Throughout this standard, reference is made to ACI and ASTM standards (listed in Appendix A [Nonmandatory]) as examples.  During the design phase of a reinforced concrete structure that could be affected by corrosion, the services of a qualified registered engineer, corrosion practitioner or corrosion specialist specializing in concrete structures 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 registered engineer, corrosion practitioner or corrosion specialist
