Grouted Post-Tensioning System (Bonded PT System)
Quite an old method.
Predominantly meant for bridge construction.
Multi-strands (many cables) are anchored with a common anchorage.
Grouting is necessary for Protection of cables (Primary Reason)restricting the movement of cable within duct to surrounding concrete.
