This paper presents an experimental investigation into the effects of chloride-induced localized corrosion on small-scale reinforced concrete (RC) beam specimens. A controlled procedure is developed to induce corrosion at predefined locations using an artificially accelerated process, combining impressed current with pre-damage cracking to simulate realistic degradation patterns. The experimental campaign examines the effects of different exposure durations (ranging from 1 to 4 months) under a constant current density of 100 μA/cm2on the corrosion morphology and the mechanical degradation of ø12 mm reinforcing bars. The results in the paper provide valuable insights for estimating the mechanical performance of corroded full-scale RC elements.

Abstract
This paper presents an experimental investigation into the effects of chloride-induced localized corrosion on small-scale reinforced concrete (RC) beam specimens. A controlled procedure is developed to induce corrosion at predefined locations using an artificially accelerated process, combining impressed current with pre-damage cracking to simulate realistic degradation patterns. The experimental campaign examines the effects of different exposure durations (ranging from 1 to 4 months) under a constant current density of 100 μA/cm2on the corrosion morphology and the mechanical degradation of ø12 mm reinforcing bars. The results in the paper provide valuable insights for estimating the mechanical performance of corroded full-scale RC elements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
