Post-Tensioned Concrete - Portland Cement Association

Post-tensioning is a method of prestressing in which the tendons are tensioned after the concrete has hardened and the prestressing force is primarily transferred to the concrete through the end anchorages. Post-Tensioning Explained Unlike pre-tensioning, which can only be done at a precast manufacturing facility, post-tensioning is performed ...
