This increases resistance to deflections and cracking caused by expansive soil problems such as lift shrinkage or swelling due to temperature or moisture changes.
There are several construction issues with post tensioned concrete that are found consistently among engineers and contractors.
Post tensioning concrete provides long term value for the following reasons.
Once the concrete has gained strength to 2000 psi typically within the 3 to 10 days recommended by pti the tendons are stressed.

Post tensioning tendons which are prestressing steel cables inside plastic ducts or sleeves are positioned in the forms before the concrete is placed.
The systems used to post tension concrete and masonry consist of prestressing steel that is housed inside a duct or sheath which allows.
Post tensioning is done at a project site and requires little to no modifications of the same forming system that would be used to construct non prestressed concrete.
Post tensioned concrete construction is a little different than standard reinforced concrete construction.
A residential post tensioned concrete slab will typically be 8 inches thick and use 3000 psi concrete.
Understanding the causes of some of these problems should help contractors build better post tensioned structures.
Post tensioning imparts an internal compressive force into the concrete.
