Video Summary

The webinar introduced updated PTI specifications for unbonded single-strand tendons: M10.2 for structural concrete and M10.6 for slab-on-ground applications. Presented by Fabrice Broussard, the session explained major 2024 changes focused on improved quality control, traceability, and corrosion protection.<br /><br />Key updates included revised reference standards, removal of outdated “normal relaxation” strand language, clearer UV protection rules for sheathing, and tighter handling requirements. The specifications now require more detailed testing records for prestressing steel, more frequent and expanded testing for PT coating, and new provisions for alternative materials if equivalency can be proven.<br /><br />For structural concrete, M10.2 added stronger traceability requirements for anchors and wedges, stricter shipping protections, new wedge hardness and quality-control criteria, and clearer execution rules such as wedge alignment, tail length limits, and timing for cutting tails, cap installation, and patching. The presentation emphasized that PTI-certified personnel should handle installation and inspection.<br /><br />M10.6 had no unique material changes beyond the shared updates, but it was highlighted as increasingly important due to new 2024 IRC provisions for post-tensioned slab-on-ground design and installation. The webinar closed with Q&A and reminders about future PTI webinars.
