Precast prestressed hollow core slabs, with their lightweight and thickness can cross spans exceptionally high.
According to the fast implementation, these slabs allow a simplification of the structure and a reduction of the building height.
Application areas:
-Office building
-Industrial buildings (factories, warehouse …)
-Commercial buildings
-Public buildings
-Schools
-Hospitals
-Hotels
Advantages of hollow core slab:
1. A highly automated production process.
2. Smooth even bottom surfaces meaning false ceilings can be omitted.
3. Good sound insulation properties.
4. Because of the longitudinal cores weight of the floor is reduced.
5. The voids in hollow core can be used for technical installations, i.e. ventilation conduits, plumbing and electrical pipes etc.
6. Short construction time, absence of scaffolding, high mechanical and durability performance, excellent span-depth ratio and good flexibility in design.
7. Hollow core can be designed to meet different fire class requirements.
8. Hollow core can be used with all types of supporting structures i.e. Bearing walls, skeletal concrete structures or steel frames.
9. The reduced weight of slabs gives savings in foundations and structures.
10. Longer spans, less support, more freedom in floor plan design.
