Corrosion Autopsy of a Structurally Unsound Bridge Deck
An investigation was performed on a 12-year old deicing salt-contaminated reinforced concrete bridge deck which had to be replaced because of its deteriorated condition. The electrical half-cell potential measurements and chloride analysis were related to massive corrosion of the steel. The effect of chlorides seems to be related to some threshold amount that changes the steel from a passive to active state. From observations of the type of cracking, it appeared that the final mode of distress was concrete fatigue. An investigation of actual concrete cover is also reported.
