Posttension
What is Posttension?
It is easy to observe the principle when loading together several books by pressing them laterally. The whole row becomes stiff and strong under such pressure, ensuring its integrity.
Bonded System
Bonded Post-Tensioning Slab System consists of fully encapsulated, bonded multi-strand (two to five strands) tendons contained in flat ducts filled with a high-performance cementitious grout that bonds the strands
Un-Bonded System
Adaptable to a variety of structures, un-bonded mono-strand post-tensioning can be easily, rapidly, and economically installed. Concrete construction applications for mono-strand systems
Advantages
- Significant reduction in the amount of concrete and reinforcing steel required.
- Thinner structural members as compared to non-prestressed concrete, resulting in lower overall building heights and reduced foundation loads.
- Aesthetically pleasing structures that harness the benefits of cast-in-place structures with curved geometries, longer cantilevers and slender members with large spaces between supports.
