Prestressed concrete - Wikipedia
Post-tensioned concrete is a variant of prestressed concrete where the tendons are tensioned after the surrounding concrete structure has been cast.: 25 The tendons are not placed in direct contact with the concrete, but are encapsulated within a protective sleeve or duct which is either cast into the concrete structure or placed adjacent to it..

Information about how post-tensioned concrete is constructed. ... at the midpoint of a beam and high at the supports—this places the steel at the point of highest tension where it can keep the concrete held together tightly. With structural members the duct is often grouted full following stressing to bond the strand to the concrete along its ....

1. Pre-tensioning vs. Post-tensioning – Ut Tensio, Sic Vis
Prestressed, post-tensioned, tendons are tensioned by a jack after the concrete has already cured (but a duct is installed such that the concrete is unbonded to the prestressing), at which time the tendons are tensioned by means of a hydraulic jack, and the beam becomes stressed. Grout may or may not then infill the ducts..

Post-Tensioning- Methods for Reinforcing Concrete - The
Post tensioning is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms before the concrete is placed. Afterwards, once the concrete has gained strength but before the service loads are applied, the cables are pulled tight, or tensioned ....
