AASHTO T 259-02 (2021) PDF Download

The AASHTO T 259-02 (2021) standard is a method used to test the resistance of concrete to chloride ion penetration. The purpose of this test is to analyze how variations in concrete properties, such as changes in cement type and content, water-cement ratio, aggregate type and proportions, admixtures, treatments, curing, and consolidation, affect its resistance to chloride ion penetration.

It is important to note that this method does not provide a quantitative measure of the expected service life of the concrete. Instead, it focuses on determining the effects of different concrete properties on its resistance to chloride ion penetration. This information can be valuable in ensuring the durability and longevity of concrete structures, particularly in environments where exposure to chlorides is a concern.
