Retard-bonded PC Strand
Retard-Bonded PC Strand is a specialized type of prestressed concrete steel strand designed with a delayed bonding performance. It features a temporary protective coating—often paraffin, wax, or other removable materials—applied over the strand surface to postpone the bonding action between the steel and surrounding concrete during construction. This allows for controlled tensioning over longer distances and enables segmental or staged construction methods. Once tensioning is complete, the strand is bonded to the concrete either by natural degradation of the coating over time or through manual removal of the protective layer prior to grouting.
