What is Prestressing and Post Tensioning?

Prestressed or post tensioned concrete is a method for overcoming concrete's natural weakness in tension. It can be used to produce beams, floors
or bridges with a longer span than is practical with ordinary reinforced concrete. 

Prestressing is where the steel wire or strand is tensioned before the concrete is poured.  Once the concrete has cured, the wire or strand are released putting the concrete into compression.  Prestressing wire and strand are used in the manufacture of precast concrete T beams for beam and block concrete floors, precast concrete hollow core, solid slabs, railway sleepers and prefabricated buildings.

Post tensioning is where the strand is tensioned after the concrete has been poured.  After the concrete has set, the strand is then tensioned and secured. Post tensioning strand is used in floor slabs for multi storey buildings, nuclear containment vessels, water tanks, natural gas tanks and many other concrete structures.
