This book was released on 2008 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
