Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during its fabrication, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of highstrength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in ...

Advantages of Prestressed Concrete The main advantages of prestressed concrete (PSC) are: Smaller Section Sizes Since PSC uses the whole concrete section, the second moment of area is bigger and so the section is stiffer: Smaller Deflections The larger second moment of area greatly reduces deflections for a given section size. Increased Spans
