Post-tensioning permits the construction of large open spaces in concrete structures and also permits slabs with a thinner profile. By eliminating interior supports and making suspended slabs lighter, you need less concrete, and the structure weighs less when complete.
The benefits of post-tensioning include:
Increased strength and stabilityPost-tensioning enhances the strength and stability of concrete structures, allowing for longer spans, thinner sections, and reduced material usage.
Improved durabilityThe high-strength steel cables used in post-tensioning resist corrosion, providing long-term durability to the structure.
Reduced crackingBy applying compressive stress to the concrete, post-tensioning reduces the risk of cracking caused by tensile stress.
Increased versatilityPost-tensioning can be used in a variety of structures, including bridges, buildings, parking structures, and more.
Reduced construction timePost-tensioning enables quicker construction times, as it eliminates the need for traditional reinforcing materials, such as steel bars.
Increased design flexibilityPost-tensioning allows for greater design flexibility, as it allows for longer spans, thinner sections, and more slender elements.
