This compression is made by the tensioning of high-power tendons Positioned within or adjacent for the concrete and is done to improve the functionality in the concrete in service.[5] Tendons could include one wires, multi-wire strands or threaded bars that happen to be most often made from superior-tensile steels, carbon fiber or aramid fiber.[1]: fifty two–59 The essence of prestressed concrete is that once the First compression is used, the resulting material has the features of superior-energy concrete when issue to any subsequent compression forces and of ductile large-energy metal when matter to stress forces.
