Corrosion Inhibiting Admixtures for Reinforced Concrete—A State of the Art Report - Item No. 21428; NACE 21428 NACE - NACE International Introduction Steel in concrete is normally protected from corrosion by the high pH of the concrete environment, which creates a stable passivation layer of iron oxides and hydroxides on the steel surface. Chlorides, however, can penetrate this layer and soluble iron chloride complexes form that weaken this layer because of the increased solubility of the iron. These iron chloride complexes allow iron to migrate from the bar surface outward in the cement paste, which leads to active ongoing corrosion of the steel. Other causes of corrosion of steel in concrete are carbonation, galvanic attack between dissimilar metals, and stray current corrosion from external sources of direct current (see ACI 222R, ACI 201.2, and NACE Publication 01110).7,10,11 corrosion inhibitors for steel in concrete are generally tested with chlorides, and some have been evaluated for carbonation-induced corrosion. Corrosion inhibitors for carbonation induced corrosion are discussed in Trabanelli (2005) and Söylev (2008).12,13 There is currently no technical information on the effectiveness of corrosion inhibitors for stray current or galvanic corrosion. Corrosion reduces the cross-sectional area of the reinforcing steel and often leads to spalling of the concrete over it because of the increased volume of the corrosion products

State of the Art Report on Corrosion-Resistant Reinforcement - Item No. 21429/21429-SG; NACE 21429 NACE - NACE International This NACE report contains information about materials that provide a corrosion-resistant alternative to plain carbon steel reinforcing bar (rebar), known also as black bar. Throughout this report the term “carbon steel bar” is used to refer to the plain carbon steel reinforcing bar. Emphasis is given on materials that have actual, or potentially, wide commercial availability. Information on fabrication, detailing, and placement of commercially available corrosion-resistant steel reinforcement is given elsewhere.1 Each material is briefly described, indicating the principles for its corrosion resistance, applicable chemical composition and standards, manufacturing method, history of application and current availability, and extent of use. Field and laboratory performance is described with attention whenever possible to quantitative consideration of the parameters that determine durability relative to that of plain carbon steel bar. ASTM(1) standards referenced in this report are listed in alphabetical order in Appendix A; however, the international user can refer to relevant standards applicable in his/her country.

Installation of Thin Metallic Wallpaper Lining in Air Pollution Control and Other Process Equipment - Item No. 21054; NACE SP0292 NACE - NACE International This standard provides technical and quality assurance guidelines for handling and installing nickel alloy, stainless steel, and titanium linings in air pollution control equipment such as FGD systems, ducts, and stacks. 1.2 The guidelines in this standard are also applicable to installation of thin, high-performance metallic linings in a wide variety of other process equipment. However, titanium welding procedures contained herein are only applicable to seal welds in air pollution control equipment. It is the responsibility of users of this standard to determine the suitability of construction materials specified for particular applications. This standard is applicable to wallpapering materials of 1.6 to 3.2 mm (0.063 to 0.13 in) thickness applied as linings over new or existing metallic structures. General safety requirements to perform this work are beyond the scope of this standard.
