Mostly, dam prestressing will take the form of submit-tensioned anchors drilled in the dam's concrete structure, the underlying rock strata, or the two. This kind of anchors generally comprise tendons of substantial-tensile bundled metal strands or personal threaded bars. A tendon is grouted to your concrete or rock at its far (internal) stop and has a big de-bonded no cost duration at its external conclude which will allow the tendon to extend during tensioning.
