Advantages of Post Tensioning
1. Material Saving
- Reduction in concrete structural element dimensions.
- Reduction in reinforcement quantities.
- Reduced dead load, reduced reinforcement and concrete in slabs, columns and foundations.
- Reduction in total building height.
2. Savings during construction
- Concrete pour cycle of 6-7 days.
- Reduction in the number of formwork/shuttering sets.
- Quick rotation of formwork sets.
- Earlier removal of formwork.
- Reduction in concrete, rebar & formwork.
- Reduction in manpower due to reduction in material.
3. Structural Performance
- Better water proofing & improved crack control.
- High deflection limitation due to concrete shrinkage and creep.
- Improvement of durability and concrete behavior.
- Increase in free space availability, greater flexibility in floor layouts and more architectural opportunities.
