Bu çalışmada 300 dozajlı, 15cm küp boyutundaki betonlara hızlandırılmış korozyon deneyi uygulanmıştır. Betonların orta noktalarına donatı çapları sırası ile ø12, ø14 ve ø16 olan donatılar yerleştirilmiştir. Üretilen betonlar kalıplardan çıkartıldıktan sonra 28 gün süre ile kür edilmiştir. Betonlarda hızlandırılmış korozyon testi yapabilmek için DC güç kaynağı vasıtası ile 30 V gerilim uygulanmıştır. Betonlara uygulanan akım ampermetre ile kaydedilmiş ve çeşitli karşılaştırmalar yapılmıştır. Beton içerisindeki donatı çapının artması ile betondaki korozyon şiddetinin azaldığı sonucuna ulaşılmıştır.

In this study, accelerated corrosion test is applied to 300 dosaged concretes whose sizes are 15cm cube. Reinforcement steel diameters of ø12, ø14 and ø16, respectively, were inserted into the middle points of the concrete. The concrete produced was cured for 28 days after being removed from the molds. In order to achive accelerated corrosion test, 30 V stress intensity is applied by DC power supply. The currents passing through the concretes were recorded with the help of ampere meter and various comparisons were made. It has been concluded that, the increase in the diameter of the reinforcement steel in the concrete can decrease the corrosion intensity of the concrete.
