Advantages of Post–Tensioned Slab

Architecture Aspect:

• Space can be easily allocated since there is no beam to limit flooring span.
• Utility space area can be adjusted according to functional variety.
• M&E layout plan can be arranged easier since there is no beam to be the obstacle.
• The buildings can be designed with longer span which make its space look more clear.

Structural Aspect:

• Post-tensioned slab provides flat and thin floor. The total weight is less than reinforced concrete (RC slab). Therefore, the construction cost of foundation work can be reduced.
• Design process is considered about fire resistance of Post-tensioned slab by defining minimum fire resistance hours according to the instruction of Post Tensioning Institute (PTI).
• The overall height of the building with the post-tensioned slab is less than the reinforced concrete slab (RC slab) in case the building has the same number of storeys. Therefore, the building can get the less effect of wind and earthquake forces.

Value:

• The height between floors is reduced. Thus, the building can be built more storeys with the same height, comparing to reinforced concrete slabs (RC Slab).
• Save material storage area. The materials can be delivered to construction site and lifted to the working floor immediately. Additionally, building can be constructed in the limited area.
• The height between floors is reduced. Vehicle ramp can be built with a short distance (vehicle ramp slope and length depending on the height between floors). Therefore, it can arrange more parking space.
• Save construction time by taking 7-10 days for construction period of Post-Tensioned slab per floor
