This compression is produced by the tensioning of large-power tendons Situated within just or adjacent into the concrete and is finished to Increase the efficiency from the concrete in company.[five] Tendons may possibly include single wires, multi-wire strands or threaded bars which can be most commonly comprised of large-tensile steels, carbon fiber or aramid fiber.[1]: fifty two–59  The essence of prestressed concrete is that when the First compression has long been utilized, the resulting content has the characteristics of higher-strength concrete when subject matter to any subsequent compression forces and of ductile significant-energy steel when topic to rigidity forces.

Failure of any of these elements can lead to the discharge of prestressing forces, or maybe the Bodily rupture of stressing tendons.

By applying a calculated amount of stretching power to your metal, the quantity of compression transmitted into the concrete may be thoroughly controlled. Prestressed concrete neutralizes the stretching forces that would rupture regular concrete by compressing a region to the point at which no tension is seasoned right until the strength from the compressed area is overcome. Because it achieves power with no working with major metal reinforcements, it's been used to excellent result to develop lighter, shallower, plus much more exquisite buildings which include bridges and large roofs.
