Contenido PTI M10.6-15: Specification for Unbonded Single Strand Tendons Used for Slab-on-Ground Construction

This specification provides performance criteria for materials and detailed recommendations for the fabrication and installation of unbonded single strand tendons specifically used in any application of slab-on-ground construction using unbonded post-tensioned reinforcement. Specifications are presented for both “standard” and “encapsulated” unbonded single-strand tendon systems.
