Post-tensioning is a construction method where steel tendons are tensioned after concrete placement to strengthen the structure.
Post-tensioning is a construction method where steel tendons are tensioned after concrete placement to strengthen the structure.
Post-tensioning uses high-strength steel strand placed inside ducts or sleeves within concrete. After the concrete cures, hydraulic stressing jacks tension the strands to apply compressive force to the structure. This improves load capacity, reduces cracking, and allows longer spans in bridges and structural slabs. Monostrand stressing jacks are commonly used for stressing individual tendons in these systems.
