Abstract:
In this study, the influences of bending crack and water-cement ratio (w/c) on the chloride-induced corrosion on main reinforcing bars and stirrups were experimentally investigated. Special features of this study include: crack formation through application of bending load, consideration of main reinforcing bars and stirrups together, and measurements of both macrocell and microcell currents. An indoor examination was conducted to investigate the corrosion of main reinforcing bars and stirrups on model beams. To clarify the indoor examination results, larger-scale beams exposed to outdoor environment were investigated. Results showing the influences of bending cracks and w/c on the corrosion rate were reported.
