ABSTRACT:
A method of and apparatus for inhibiting the corrosion of a tendon within a post-tensioning anchor plate assembly. A tubular extension member protects the tendon and includes a foam injection port which is adapted for the injection of foam material to inhibit tendon corrosion, when it is sealed against the anchor plate. The tubular extension member further includes a circumferential ring disposed therearound providing a water stop to the infiltration of moisture after construction of the post-tensioning assembly. An anchor plate cap is also provided for covering the terminal end of the post-tensioned tendon. The cap is constructed with a radially extending ridge disposed along the inner edge for interlocking engagement with the anchor plate. A round die cut foam insert is provided in the cap to seal the terminal end of the tendon.
