In this study, the effects of the use of chemical additives and corrosion inhibitors on the durability of the concrete and the corrosion of the reinforcement in the concrete were experimentally investigated. In this context, the effects of inhibitors used to prevent corrosion were investigated and the effect of boron inhibitor in preventing corrosion was revealed. The inhibitor produced from natural boron was used instead of concrete additives known for its toxic and chemical effects. In the study, reinforced concrete samples were produced with concrete mixtures prepared with four different chemical additives and two different corrosion inhibitors. The chemical additives used are set accelerator, set retarder, super plasticizer, hyper plasticizer. Corrosion inhibitors are calcium nitrite-based corrosion inhibitör and inhibitor obtained from natural boron. It has been observed that the use of corrosion inhibitors improves the durability properties of concrete. It has been understood that the concrete properties when used together with chemical additives and corrosion inhibitors give much better results than when these additives are used alone. Among all series, the concrete sample containing boron and hyper plasticizer provided significant corrosion protection by reducing the initial corrosion current by 56.2%. Moreover, the latest damage occurrence time was found as samples contained boron inhibitors with 361 hours as a result of the accelerated corrosion tests.
