Description of ASTM-G109 2013ASTM G109 - 07(2013)Standard Test Method for Determining Effects of Chemical Admixtures on Corrosion of Embedded Steel Reinforcement in Concrete Exposed to Chloride EnvironmentsActive Standard ASTM G109 | Developed by Subcommittee: G01.14 Book of Standards Volume: 03.02 ASTM G109Significance and Use 3.1 This test method provides a reliable means for predicting the inhibiting or corrosive properties of admixtures to be used in concrete. 3.2 This test method is useful for development studies of corrosion inhibitors to be used in concrete. 3.3 This test method has been used elsewhere with good agreement between corrosion as measured by this test method and corrosion damage on the embedded steel ( 1- 4 ). 5 This test method 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 ). 1. Scope 1.1 This test method covers a procedure for determining the effects of chemical admixtures on the corrosion of metals in concrete. This test method 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 are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use.
