This compression is produced by the tensioning of higher-power tendons located within just or adjacent into the concrete and is done to Enhance the overall performance in the concrete in support.[5] Tendons may encompass one wires, multi-wire strands or threaded bars which can be most commonly made out of substantial-tensile steels, carbon fiber or aramid fiber.[1]: fifty two–fifty nine The essence of prestressed concrete is that after the Original compression has actually been utilized, the resulting material has the features of significant-energy concrete when topic to any subsequent compression forces and of ductile significant-energy steel when subject to pressure forces.
