Abstract: A tendon suitable for posttensioning concrete and for use in other applications comprising a multiple-wire strand incased in a corrosion inhibitor in an amount sufficient to provide a circular enclosure greater than the outside diameter of the strand and having a seamless plastic jacket tightly covering said incased strand. A process of making said tendon which comprises the steps of coating and filling the interstices of a multiple-wire strand with a corrosion inhibitor, passing same through a circular die of a diameter greater than the strand to remove excess corrosion inhibitor and to form a circular enclosure of said inhibitor around said strand, and melt extruding a plastic jacket around said incased strand.
