By admin, on July 28th, 2011 On rare occasions, the ironworker/installer will need to detension an already-stressed post tensioning tendon. The reason may be due to a repair procedure or re-stressing due to out-of-range elongation readings.
Recommendations:
- During the detensioning process, the post-tensioning tendon will have to be “over-stressed.” The PTI Field Manual recommends that the hydraulic jack and pump gauge pressure should not be taken more than 5% over the normal stressing gauge pressure (at 33 kips of 0.5″ tendon).
- The jack should be opened at least 4 inches so that it does not get “hung up” in case the wedges fail.
- The detensioning procedure be performed shortly after the normal stressing operation. Over time, the wedges deformed inside the anchor cavity and form a “lock” with the strand and anchor. (Refer to the PTI Field Manual 3rd Edition section 10.9).
The pictures below show an example of how to detension the tendons with a Detensioning Tool.
 Place detensioning tool level with anchor cavity and strand. Secure hydraulic jack behind detensioning tool.
 Extend Hydraulic Jack to unseat wedges. This follows the normal stressing procedure. Hold gauge pressure at 5% overstress.
 Use pliers (and magnet) to take wedges out of anchor cavity. Do not use your fingers. Failure to use the proper parts or equipment could result in damaging the anchor, strand, equipment or harming the operator/by-standers. This procedure should be carried out by a Post-Tensioning Institute Certified Ironworker (level 2). This post is not a complete procedure for detensioning PT tendons. Proper jobsite precautions should be taken to restrict personnel during stressing and detensioning processes.

By nkhosa, on July 2nd, 2011 Hiring a quality Unbonded Post-Tension Supplier can be the difference between a smooth construction project and a problematic situation. The Post-Tension (PT) supplier will play a key role in your reinforced concrete project. Therefore, general contractors and concrete contractors need to choose wisely.
Traditionally, the Post-Tension Supplier is awarded their contract after other subcontractors in larger trades have been selected. Finding the right PT supplier to work with is essential to completing your concrete construction project on time and within budget.
Aside from checking whether the project has been bid per specifications, the following are some questions to ask PT suppliers before awarding the job:
What is your proposed pour sequence?
Unless the construction joints and pour numbers have been referenced on the structural drawings, a PT supplier will have to assume a pour sequence for bidding purposes. If you and your PT supplier had different pour sequences in mind, then time may be wasted in the shop drawing stage. It’s best to be on the same page prior to the contract award.
How many trucks (or deliveries) have you included in your proposal?
If your construction site has limited lay-down areas, then you may not want full truck-load deliveries from your PT Supplier. Your PT Supplier should provide the construction materials per your schedule, but it’s always good idea to let them know the plan.
What previous PT projects have has the PT Supplier worked on that are similar to this project?
Whereas having the lowest price is important during bidding, but hiring a Post-Tensioning Supplier with the right expertise could help you avoid losing money during construction. There may be unique challenges in your construction project that need to be overcome in a timely and cost-effective manner. As with other construction trades, experience matters.
How many sets of stressing equipment will you provide and for how long?
Most PT specifications require at least 2 sets of stressing equipment at the construction site. If one set goes down, then having a backup set can help maintain the schedule. For larger projects with multiple crews, a contractor may require more than 2 sets. As with other rented equipment, the rental period may vary depending on the duration of the project.

By nkhosa, on June 22nd, 2011 Having clean anchor cavities is one of the most important part of getting proper elongations of unbonded post-tensioning tendons.
 Post-Tension Stressing Tails - side  Post-Tension Tendon Stressing Tails Since construction is not the cleanest of jobs, there may be debris inside the PT anchor cavity. A major cause of under-elongations and/or strand-slippage is due to having debris (concrete, dirt, mud, etc.) inside the PT anchor cavity. The debris doesn’t allow the wedges to seat properly (the wedges are inside the anchor cavity and hold the strand in place after the stressing operation). If enough tendons have under-elongations, then the structure may not have enough force within the concrete member. Therefore, it is important to have clean anchor cavities prior to stressing operations.
 Post-Tension Anchor Cavity  Post-Tension Anchor Cavity - closeup In order to clean the post-tension anchor cavities prior to stressing (and installation of wedges), we recommend spraying WD-40, or approved equal, into the anchor. This non-corrosive chemical should dislodge any loose debris. Afterwards, the strand and anchor cavities should be cleaned prior to the installation of the wedges and the stressing operations. (Note: The WD-40 should be compatible with the post-tension grouting used to fill the anchor cavity. The anchor cavity must be clean in order for the grout to bond properly.)
