- Column free space/Larger span for IT Parks, commercial/shopping complexes.
- Speedy Floor to Floor construction cycle time( 10 days per slab) due to simplified Formwork
- Reduction in Dead load due to Thinner slab which will make cost savings in Foundation & Columns
- Due to Post Tensioning, earlier strip- ping of formwork i.e., below 10 days, thus achieving higher recycling of shuttering.
- Reduction of reinforcement Quantity and easy handling of Post- Tensioning Materials in congested site areas.
- Less no of work force engaged for Post Tensioning works than RCC slabs.
- Reduction in overall building Height, thereby additional floors are possible
- Reduction of cost in vertical structur- al element
- Flexibility for providing service ducts and False ceilings.
- Greater Flexibility for penetrations and openings in floors, both pre and Post Construction
Earlier Stripping Of Shuttering
Post-tensioned slab would be ready for stressing operation when concrete strength achieves 25 N/mm2. For a concrete grade of 35 N/mm2, this normally happens on the 7th day after concreting.
Upon completion of stressing, all the slab shuttering can be removed and recycled for other slab’s concreting. This earlier stripping of shuttering would mean that the builder would need less shuttering materials and the finishing work at the lower floors can be carried out earlier.
