post-tensioning techniques

Post-tensioning is a construction method where steel tendons or cables are installed into the concrete after it has hardened. These tendons are tensioned or stretched using hydraulic actuators, then anchored to the concrete, creating compressive forces that strengthen the structure. This technique allows for longer spans, thinner slabs, and enhanced durability by reducing cracks and stresses. Post-tensioning is commonly used in bridges, parking garages, and large buildings, offering increased strength and flexibility while using less material compared to traditional concrete construction.
