What Is Prestressed Concrete How Does It Work Civil

What Is Prestressed Concrete How Does It Work Civil

Pre-stressed concrete is a form of concrete where initial compression is given in the concrete before applying the external load so that stress from external loads are counteracted in the desired way during the service period. This initial compression is introduced by high strength steel wire or alloys called tendon located in the concrete section.
