ABSTRACT:
An anchor apparatus which provides corrosion protection for the exposed cable in a region around where the anchor body attaches to a tendon of a prestressed concrete slab is disclosed. A conduit is fastened to the inlet end of the anchor body. The other end of the conduit is taped or connected with heat shrink tubing to the covering of the tendon. The outlet end of the anchor body is closed either with a plug at an end anchor or with a second conduit and tape or heat shrink tubing at an intermediate anchor. Fittings are provided for inserting corrosion resistant grease into interior cavities as a second line of corrosion protection.
