Influence of pits characteristics on the failure mode of viaduct in service steel rebars

In the present work, the failure mode of rebars extracted from a reinforced concrete viaduct suffering corrosion in Spain has is studied. It has been confirmed the validity of the strategy based on performing hardness sweeps along a diameter of the bars for determining the mode of failure suffered i...
