Identification of the failure mode of corroding steel rebars in a viaduct in service through hardness measurements

In the present work, rebars extracted from a reinforced concrete viaduct that had to be demolished has been studied because they broke in service with an unusual tilted pattern for the rebars without reduction in diameter. The structure was a bridge suffering alkali-silica reaction and reinforcement...
