US - Corrosion of Bridges - Corrosion threat on Skyway bridge deck discovered in Ohio. High level of salts in grout feared

Grout packed into bundles of steel cables that compress the Veterans' Glass City Skyway's concrete deck sections together may contain elevated levels of salts that would cause those cables to corrode prematurely, the grout's manufacturer has warned the Ohio Department of Transportation.

The I-280 bridge over the Maumee River, which opened five years ago, is one of several dozen projects across the United States that used grout made at a Marion, Ohio, plant owned by Sika Corp. U.S. in which excessive chloride compounds, traced to cement the plant bought from an unnamed supplier, have been discovered.
