Standard Test Methods for Determining Effects of Chemical Admixtures on Corrosion of Embedded Steel Reinforcement in Concrete Exposed to Chloride Environments

SIGNIFICANCE AND USE
3.1 These test methods provide a reliable means for predicting the inhibiting or corrosive properties of admixtures to be used in concrete.  
3.2 The total integrated (coulombs) current is calculated to provide an indication of the corrosion that occurs due to the macrocell corrosion.  
3.3 These test methods are useful for development studies of corrosion inhibitors to be used in concrete.  
3.4 These test methods have been used elsewhere with good agreement between corrosion as measured by these test methods and corrosion damage on the embedded steel (1-4).4 These test methods might not properly rank the performance of different corrosion inhibitors, especially at concrete covers over the steel less than 40 mm (1.5 in.) or water-to-cement ratios above 0.45. The concrete mixture proportions and cover over the steel are chosen to accelerate chloride ingress. Some inhibitors might have an effect on this process, which could lead to results that would differ from what would be expected in actual use (5).
SCOPE
1.1 These test methods cover a procedure for determining the effects of chemical admixtures on the corrosion of metals in concrete. These test methods can be used to evaluate materials intended to inhibit chloride-induced corrosion of steel in concrete. It can also be used to evaluate the corrosivity of admixtures in a chloride environment.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
