A Test of Reinforcement Corrosion Progress in the Presence of Organic Corrosion Inhibitors

Test results for KCR and DME migrating inhibitor efficiency are presented. The method of linear polarization is used in the tests on loaded reinforced concrete elements. Various durations of inhibitor activity, cracked concrete cover and different levels of reinforcement corrosion development in test parts are taken into account. The inhibitors are only partly efficient at low levels of corrosion development at an early stage, however, after two years the protective work is not verifiable. In the case of intense reinforcement corrosion a reduction in its degree is not observed, even directly after inhibitors have been applied.
