Corrosion Resistance of Concrete
The depth of chloride intrusion is measured over time (beginning at 35 days soaking period) by grinding away successive layers from the specimen and then measuring the chloride level of each layer using ASTM C1152, Standard Test Method for AcidSoluble Chloride in Mortar and Concrete. This procedure gives a direct correlation to the permeability of the concrete and is considered a useful method for .
