Strand concrete
WebThe prestressing steel strands are accumulated in separate tendons and exert compressive stresses along the crosssection. This design prevents cracks from developing along the … WebOnce after the concrete has achieved its 75% of strength , that is around 20 - 23 days, these tendons are stressed with the help of stressing jacks. The tensioning is done to a force equal to 80% of a strand's tensile strength. For a typical ½-inch grade 270 strand, the strand is tensioned to a force of 33,000 pounds.
