Acceptance Tests for Surface Characteristics of Steel Strands in Prestressed Concrete

This report provides practical tests to identify and measure residues (e.g., rust, lubricants used in manufacturing processes, or corrosion inhibitors) on the surface of steel prestressing strands and to establish thresholds for residue types found to affect the strength of the strand's bond to concrete. Key products presented here are four test methods suitable for use in a quality assurance program for the manufacture of steel prestressing strand. The report will be of particular interest to bridge engineers in state highway agencies and industry and to suppliers of steel prestressing strand.
