The essential component of a post-tensioning system is known as a tendon. A post-tensioning tendon is comprised of a piece of prestressing steel housed inside a duct or sheathing. A tendon has anchors on each end to transfer the force into the structure.
Post-tensioning tendons require exceptional expertise and training by for handling that is only offered by a qualified post tensioning company. Experts form post tensioning company will install the tendons in the exact locations as directed by the architect or as they appear on the post-tension field placement drawings. Once poured, the post tensioning company ensures that post tensioning tendons must not be moved or disturbed till the time they set properly. In elevated slab construction, the tendons are placed together in groups so that the space between tendons is increased which improves the constructability of the slab.
After the concrete is set, it must achieve desired quality before the tendons are tensioned. A hydraulic jack is used by post tensioning company for tensioning of the tendons. The force created when the tendons are tensioned is sufficiently high to damage the structure or even cause damage to individuals working at the site if not done properly. The post tensioning company makes sure that there is nobody working in the area where the tendon is being stressed.
The elongation of the steel is then measured by post tensioning company and recorded for each tendon. It is checked against the specifications to make sure that it is as desired. When the measurements have been verified, the stressing tails can be cut off at the edge of the concrete slab and the gap is filled with non-shrink grout for cover and protection.
