PURPOSE: A nonmetallic anchorage for a prestressed concrete structure is provided to reduce maintenance costs for a structure by increasing durability of a structure and improving corrosion resistance of a tendon and an anchorage, and to improve structural stability of a prestressed concrete structure. CONSTITUTION: The nonmetallic anchorage(100) for a prestressed concrete structure(400) comprises: a nonmetallic sleeve(10) connected with a duct(60) for inserting a tendon and provided with a stopping stiffener(20); packing materials(30) for preventing a flow of expansion materials on both ends of the sleeve; an injection pipe(40) for expansion materials and an air exhaust pipe(50) formed on the packing materials exposed to the outside; a nonmetallic tendon(200) interposed to the duct(60) and the nonmetallic sleeve(10); and expansion materials(300) injected through the injection pipe(40).
