Inland Steel Building, Chicago, IL
|
Extensive field and laboratory evaluation of the problem with ongoing corrosion of the major steel columns in this twenty story, landmark building. due to the presence of calcium chloride in the lightweight concrete fireproofing that surrounds the columns. The work was performed to determine the cause of the corrosion, the extent of the damage that may have occurred to date, and whether or not corrosion activity was still present and expected to continue in the future.
The corrosion was determined to be caused by the presence of calcium chloride in the lightweight concrete fireproofing which surrounds the columns. The corrosion was occurring in areas where water was infiltrating through the stainless steel column enclosures. |
