Why Post-Tensioned Concrete Is Important?

Post-tensioning, which is a form of prestressing, has several advantages over standard reinforcing steel (rebars): It reduces or eliminates shrinkage cracking-therefore no joints, or fewer joints, are needed. Cracks that do form are held tightly together. It allows slabs and other structural members to be thinner.

What is the purpose of post-tensioning concrete?

Designers use post-tensioning as a way to reinforce concrete by prestressing it. In prestressed members, compressive stresses are introduced into the concrete to reduce tensile stresses resulting from applied loads including the self weight of the member (dead load).

Is post tension slab necessary?

Post-tensioning provides high strength and stability, but looks just like any other concrete slab. While most home projects don't require post-tensioning, it could still be a useful technique for some builders.
