Corrosion of steel generates iron oxides and hydroxides, in the increase of volume 5 to 8 times its original size. This increase in volume causes expansive forces to accumulate within the concrete around reinforcement and results in cracking and in areas with low cover, concrete spalling. Cracks provide easier access to oxygen, moisture, chlorides and other corrosive agents, creating conditions suitable for accelerating electrochemical corrosion.
Pretensioned concrete bridge girders may exhibit unexpected end cracking upon pre-stress release. Leakage from the bridge expansion joint could penetrate the bottom flange cracks and trigger severe corrosion. In this case, the expansion joint leakage must be arrested before the crack and concrete repair activity.
