An assembly for use in the post-tensioning of prestressed concrete comprising (a) spaced building forms between lwhich concrete is to be poured, (b) a dead end anchor adjacent one of said forms, (c) a live end anchor adjacent the other of said forms in opposed relation to said dead end anchor,

Prestressed concrete is structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads. This introduction of internal stresses is called “prestressing” and is usually accomplished through the use of tendons that are tensioned or pulled tight prior to being anchored to the concrete.
