Sažetak
Reinforced concrete is widely used as a building material and plays a significant role in economic development. However, the premature degradation of reinforced concrete structures due to the reinforcing steel corrosion has become a serious problem in modern society, which results in a huge economic loss. Application of corrosion inhibitors, both, admixed and topically applied, is recognized as a mean of fighting reinforcement corrosion. The applicability of electrochemical impedance spectroscopy (EIS) for rating inhibitor efficiency, in a cell consisting of steel plate covered by a concrete layer containing chlorides and inhibitor, constructed in accordance with EN ISO 16773, has been tested for the first time. The measurement results have enabled: quantification of chloride action and inhibitor efficiency, clarification of mechanism and time dependence of inhibitory activity, separation of effects the inhibitor exerts on concrete itself and on steel/concrete phase boundary and visual inspection of metal surface after the measurement. Besides EIS, corrosion potential has also been recorded and contact angle and free surface energy on concrete samples have been measured. The obtained results are consistent with the presumed physical model while demonstrating the efficiency of the inhibitors and differences between them and confirming the applicability of the developed method. The proposed procedure yields reproducible results very fast and has large potential to enter in use alongside the widespread ASTM G109 method.
