    摘要: An unbonded PC steel strand used for posttensioning concrete comprising a PC steel strand composed of a plurality of stranded wires, a thin transparent lacquer coating on the outer surface of the PC steel strand, the lacquer coating being able to be broken when the PC steel strand is subjected to tension or posttensioning concrete, a filler applied around the lacquer coating, and a synthetic resin sheath covering the lacquer and filler coated PC steel strand. A method of manufacturing the unbond PC steel strand comprising steps of annealing the PC steel strand at a low temperature to remove strain, coating the outer surface of the PC steel strand with lacquer, applying a greaselike corrosion inhibitor to the surface of this lacquer coating, and sheating the coated PC steel strand with an outer synthetic resin sheath.

    摘要: 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.
