Slab System Concrete Requirements for Early Age Stressing

Post-tensioned concrete relies upon the transfer of the prestressing force into the surrounding concrete. This process occurs early in the life of a structure and therefore the specification of the concrete performance is critical.

Standard Slab System Helical Anchorage Reinforcement

Post-tensioning of concrete relies on the transfer of the stressing force from the high tensile steel tendons to the surrounding concrete. This is achieved by the use of post-tensioning anchorages.
