The No. 1 ore dock at Great Lakes Steel Division's Zug Island facility was originally constructed in 1909. Damage caused by freeze-thaw cycling, abrasion wear, severe impact loadings, and reinforcing steel corrosion resulted in a need for repair and rehabilitation. Multiple Dynamics Corporation conducted extensive condition surveys and testing to develop repair strategies for this structure. The remaining service life was then predicted to assist in economic planning. This case history provides an excellent example of concrete performance in an aggressive environment.
