Concrete, repairing materialsand protective coating: Carbonation resistance (NT BUILD 357)

NT BUILD 357

  • The resistance against CO2-penetration through concrete repairing materials and concrete protective coating is determined by an accelerated laboratory test on laboratory prepared samples by exposing the samples to carbon dioxide enriched air in order to evaluate the effect of concrete repairing materials. The depth of CO2-penetration is measured by the phenolphthalein method.
