Abstract:

Damage to in reinforced concrete structure caused by chloride-induced steel reinforcement corrosion in concrete is a serious source of concern for the structure long-term durability. Various methods have been developed to protect this steel in concrete against corrosion. In this study, corrosion inhibitor was used as a protection method. The effect of the corrosion inhibitor used on steel corrosion and concrete-steel adherence was investigated. In the study, reinforced cube samples of 15 cm dimensions were produced. A total of four different curing periods, 7, 28, 90 and 180 days, were applied to the samples in which 1% of the cement by weight calcium nitrate-based corrosion inhibitor was used in the concrete mixture, in the saltwater curing solution prepared based on seawater. In order to learn the corrosion activities of the produced samples, half-cell potential and pull-out test was applied to determine the adherence strength. As a consequence of the experimental tests, it was observed that the corrosion probability in the samples using inhibitor is lower than the samples without inhibitor. In addition, it was concluded that the adherence strength of the samples using inhibitor was higher.
