Bibliography

This European Standard defines: A test method for determining the influence of an admixture on the corrosion of a steel bar embedded in a mortar sample held at an increased potential in an electrochemical cell. The method can be used to determine the harmlessness of admixtures with regard to corrosion of reinforcing but not stressed steel. It applies to all admixtures for concrete, mortar and grout in contact with reinforcing steel.NOTE 1This test method does not apply to assessing corrosion behaviour of admixtures when used with high tensile steel.NOTE 2This test method does not assess the efficacy of admixtures defined as corrosion inhibitors.NOTE 3The quantity of chloride ion present in admixtures is covered by a separate requirement in the relevant parts of the EN 934 series.
