Post-tension cables are used in concrete construction to add strength to thin and long slabs. This allows for longer spans between support columns. The cables have steel wires within the plastic sheath. They are tensioned after pouring concrete. Post-tension ‘tendon’ is a term used to define the complete assembly comprising of the sheath, pre-stressing strand, anchorages, corrosion-inhibiting coating, or any grout around the steel wire or bar.
Post-tensioning cable involves reinforcing concrete using high-strength steel strands. The steel strands are commonly called ‘tendons’. It is used in a wide range of concrete structures including:
Post-Tensioning (PT) estimation covers involve calculating the materials and labor required for a post-tensioning system in concrete structures, typically used for slabs, beams, or bridge decks. Post-tensioning involves the use of high-strength steel tendons (cables) that are tensioned after the concrete has set.
It allows the construction of structures that would otherwise be impossible.
