PRESTRESSING MATERIALS. SITE HANDLING AND STORAGE

This article provides a summary of the precautions which are necessary to protect prestressing steel, tendons, ducting and anchorage components against damage and unacceptable deterioration from the time of delivery to site by the manufacturer until the time of prestressing. Also included is a short explanation of the main forms of corrosion. The most common problems are mechanical damage which may arise from inadequate storage and handling arrangements, and heating, which may be caused by unsuitable cutting procedures or splatter from nearby welding activities. A list of general recommendations is provided first, including advice about handling and storage. Recommendations for specific prestressing materials, such as wire and strand, bar, prestressing anchorages, and ducting are then presented. Some protective measures which can be used to prevent corrosion by controlling the relative humidity adjacent to the steel are also presented. (TRRL) (Author/TRRL)
