ASTM G109-21 PDF Download

ASTM G109-21 standard provides a procedure for assessing the impact of chemical admixtures on the corrosion of metals in concrete. The test methods outlined in this standard are specifically designed to evaluate materials that are intended to inhibit chloride-induced corrosion of steel in concrete. Additionally, these methods can also be used to determine the corrosivity of admixtures when exposed to a chloride environment.

In summary, ASTM G109-21 is a standard that establishes guidelines for conducting tests to assess the effectiveness of chemical admixtures in preventing corrosion of embedded steel reinforcement in concrete. This standard is applicable for evaluating materials used in concrete construction projects that are exposed to chloride environments, such as coastal areas or environments with de-icing salts.
