    Abstract: A non-destructive test method for evaluating a synthetic rope made of strength member elements includes: treating at least one strength member element to be detectable by a magnetic NDT device, incorporating the at least one treated strength member element into the rope, scanning the synthetic rope with the magnetic NDT device, and obtaining magnetic flux leakage or eddy current output data from the magnetic NDT device, wherein the output data relates to a condition of the synthetic rope. A synthetic rope or cable is thereby made to be capable of being inspected by a magnetic flux leakage or eddy current non-destructive test (NDT) method.

    Abstract: An unbonded PC steel strand used for posttensioning concrete comprising a PC steel strand composed of a plurality of stranded wires, a zinc plated layer on the outer surface of the PC steel strand, a greaselike filler applied around the zinc plated layer, and a synthetic resin sheath covering the zinc and filler coated PC steel strand. A method of manufacturing the unbonded PC steel strand comprising steps of pickling and water washing the PC steel strand, coating the outer surface of the PC steel strand with flux, plating the outer surface of the PC steel strand with zinc, applying a greaselike corrosion inhibitor to the surface of the zinc plated layer and sheathing the PC steel strand with an outer synthetic resin sheath.
