Acceptance Tests for Surface Characteristics of Steel Strands in Prestressed Concrete

TRBs National Cooperative Highway Research Program (NCHRP) Report 621: Acceptance Tests for Surface Characteristics of Steel Strands in Prestressed Concrete explores tests to identify and measure residues on the surface of steel pre-stressing strands and to establish thresholds for residue types found to affect the strength of the strands bond to concrete.
