Influences of bending crack and water-cement ratio on chloride-induced corrosion of main reinforcing bars and stirrups

In this study, the influences of bending crack and water-cement ratio (w/c) an the chloride-induced corrosion on main reinforcing bars and stirrups we re experimentally investigated. Special features of this study include: cra ck formation through application of bending load, consideration of main rei nforcing 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 an out-door environment were investigated. Results showing the influences of bending cr acks and w/c on the corrosion rate were reported.
