Concrete slab reinforced with tensioned cables
What is a post-tension slab
Post-tensioning (or prestressing) is a process that uses high-strength materials such as cables to reinforce the structural elements of a construction. After casting, the strands in cables are tensioned at the appropriate pressure to apply a compression force on the concrete and increase its capacity.
This Technology is the preferred solution when it comes to thin structural elements. In addition, it promotes a faster floor cycle time, allowing the structure to progress more rapidly and buildings will be more earthquake resistant.
Bonded and unbonded post-tension system
Full ranges of tendon sizes of 0.5" strands and 0.6" strands.
Advance stressing jacks equipped with automatic stressing heads and power wedge seating devices.
Anchorage adaptable for both strand of 0.5" (12.7mm., 12.9 mm.) and 0.6" (15.24 mm., 15.7 mm.) according to standard ASTM A416 or BS 5896.
ADVANTAGES OF POST–TENSIONED SLAB
- Architecture
- Structural
- Value
- Space can be easily allocated since there is no beam to limit flooring span.
- Mechanical and electrical layout plans can be arranged easier
- The buildings can be designed with longer span
- Achievement of complex geometry and special design challenges that meet all the needs of modern architecture
- Reduction in self weight due to thinner slab
- Reduced building mass especially significant in high seismic zones
- Reduced cracks occurrence.
- Improved deflection criteria
- The overall height of the building with the post-tensioned slab is less than the reinforced concrete slab. Therefore, the building can get the less effect of wind and earthquake forces.
- The height between floors is reduced.
- Maximum flexibility for buildings
- Faster construction cycle reducing duration of formwork, scaffolding and manpower
- Economical as lesser reinforcement and concrete is used
- Larger column free space
- Less no of work force engaged for Post tensioning works than conventional slabs
