(57) An anchor assembly for use with a tensioning strand includes an anchor body including a bore therethrough, the bore configured to receive the strand therethrough, an inner surface of the bore including a frusto­conical wedge-receiving cavity, at least one frustoconical wedge including a strand-engaging inner surface and an anchor body engaging outer surface, the wedge being at least partially received in the wedge-receiving cavity, an encapsulating layer at least partially surrounding the anchor body, and a wedge retention disk mechanically coupled to the anchor body and positioned so as to pre­vent the wedge from fully exiting the wedge-receiving cavity. The wedge retention disk may be spaced apart from the anchor body such that the wedge can move axially with respect to the anchor body between a seated position in which the wedge engages the wedge-receiv­ing cavity and an unseated position in which the wedge engages the wedge retention disk.
