Prestressed concrete – Wikipedia
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 high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in …
