Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. This compression is produced by the tensioningof high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the con
