Abstract
SUMMARY
The chloride ion permeability of concrete repairing materials and concrete protective coating is determined by an accelerated laboratory test where a direct current voltage is applied between a steel rod embedded into the specimen and the specimen surface in order to evaluate the effect of concrete repairing materials.
SCOPE
This method specifies an accelerated laboratory test procedure to determine the resistance against chloride penetration through concrete repairing materials and concrete protective coatings in order to evaluate the effect of concrete repairing materials. It consists of monitoring the time to failure or reinforced concrete specimens exposed to an electric field.
FIELD OF APPLICATION
The method can be used to compare both concrete repairing materials and concrete protective coatings.
