ABSTRACT

To increase the tensile strength of reinforced concrete structures, strengthening steels of different diameters are placed in the concrete. The diameter of the reinforcing steel to which placed in the concrete may decrease due to electrochemical reactions. Therefore, the determination of corrosion rates in structures is vital for solving this problem. As the corrosion rate increases, flexibility and ultimate load carrying capacity decrease. In this study, reinforcing steel of 12, 14, and 16 diameters was placed in the middle of the concretes and subjected to an accelerated corrosion test by applying a 30 V direct current (DC). When DC was applied to concrete, weight loss values, crack widths, compressive strengths, tensile strengths, and micro examination results were compared. As a result, it has been seen that the corrosion rate decreased as the diameter of the reinforcement steel increased. Another result obtained from this study is that the corrosion level could be predicted by measuring the current flow over the reinforcing steels. It has been observed that microcracks occur much less than when 14 reinforcement was placed compared to 12 and 16 reinforcements were placed in concretes.
