C09 standardizes electrical current-based permeability measurement

Sources: ASTM International, West Conshohocken, Pa.; CP staff

ASTM Committee C09 on Concrete and Concrete Aggregates’ new C1876-19 standard presents a test method aimed at improving concrete durability assessment through measuring resistance to electrical current flow. Ability to resist such currents, along with exposure to aggressive fluids, depends on concrete pore size and porosity.
