Standard Test Method for Corrosion Inhibiting Admixtures for Steel in Concrete by Polarization Resistance in Cementitious Slurries

Importancia y uso:

4.1 This test method provides a means for assessing corrosion-inhibiting concrete admixtures.

4.2 This test method is useful for development of admixtures intended to reduce corrosion of reinforcing steel in concrete.

4.3 This test method is useful in determining the corrosivity of admixtures toward steel reinforcing if the admixture sample is compared to a control without admixtures.

4.4 Good performance, a reduction in corrosion rate versus chloride alone by at least one order of magnitude in this test, is a strong indication that an admixture is a corrosion inhibitor. However, poor performance requires additional testing to determine if the admixture improves corrosion resistance.

4.5 This test method shall not be used to predict performance in the field.

4.6 The filtering process makes this test not suitable for the evaluation of emulsions.
