“…The solution level in the tanks was controlled to be about 30 mm lower than the lower surface of the rebars, as shown in Figure 3. In the previous studies on mechanical properties of corroded rebars, accelerated corrosion by means of the impressed current technique is widely used to obtain corroded rebars because of its advantages in terms of time and cost, and its feasibility to control the rate of corrosion [18,19]. There are some differences between accelerated corrosion and natural corrosion in corrosion products, distribution of corrosion expansion force, and distribution of bond stress [20].…”

“…Dabei weisen die Ergebnisse dieser Untersuchungen auf einen linearen Zusammenhang von Restquerschnitt und Höchstzugkraft hin. Dies deckt sich mit Feststellungen von Ou et al , die aufzeigen, dass die Tragfähigkeit überwiegend durch einen einzigen Faktor, nämlich den kleinsten maßgebenden Querschnitt, bestimmt wird.…”

“…Dies liegt in den unterschiedlichen Berechnungsarten der jeweiligen Bezugsquerschnitte bei den verschiedenen Untersuchungen begründet. So stellen Ou et al unter Verwendung des Nennquerschnittszur Festigkeitsberechnung verständlicherweise fest, dass mit zunehmendem Korrosionsgrad eine abnehmende Zugfestigkeit einhergeht. Betrachtet man aber die Ergebnisse von Almusallam oder Zhu et al , zeigt sich, dass der Korrosionsgrad bei Berücksichtigung des kleinsten Restquerschnittseiner Probe im Allgemeinen nur einen relativ geringen Einfluss auf die effektive Zugfestigkeit hat.…”

“…The experimental component of this investigation included a total of three circular RC columns, with two of the columns being corroded using an accelerated corrosion technique called impressed current method. Past studies used the impressed current method for corroding RC concrete members to predict residual lifetime of corroded RC structures . The noncorroded column and the corroded columns were placed horizontally and cut at the middle to provide six specimens with identical height.…”
