Significance 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 (1.1 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. |
