What are the advantages of prestressed concrete? - Quora

Prestressed concrete is structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads. This introduction of internal stresses is called “prestressing” and is usually accomplished through the use of tendons that are tensioned or pulled tight prior to being anchored to the concrete.
