Description

Post-tensioning is a method of producing prestressed concrete, masonry and other structural elements. The term prestressing is used to describe the process of introducing internal forces (or stress) into a concrete or masonry element during the construction process in order to counteract the external loads that will be applied when the structure is put into use (known as service loads). These internal forces are applied by tensioning high strength steel, which can be done either before or after the concrete is actually placed. When the steel is tensioned before concrete placement the process is called pre-tensioning. When the steel is tensioned after concrete placement the process is called post-tensioning of RCC
