ASTM C70 (Test Methods for the Effect of Soluble Salts on Concrete)

ASTM C70 is a standard that outlines how to test concrete for the presence of soluble salts, which can harm the material over time. These salts can come from various sources, such as deicing agents or seawater, and may cause issues like corrosion of steel reinforcement or surface spalling. The test methods specified in ASTM C70 help determine the type and amount of soluble salts in concrete. Understanding these factors is essential for ensuring the durability and longevity of concrete structures, particularly in environments where exposure to salts is likely.
