The document discusses bubble deck slabs, which are hollow concrete slabs that use plastic spheres to replace ineffective concrete. There are three main types - filigree elements, reinforcement modules, and finished planks. Bubble deck slabs are lighter than traditional slabs, stronger, allow for larger spans, and use less material. They also provide benefits like reduced construction time and costs as well as being more environmentally friendly through lower CO2 emissions.

4. Introduction
• The Bubble Deck system is based upon the patented integration
technique - the direct way of linking air and steel.
• The Bubble Deck is a two-way hollow deck in which plastic balls
serves the purpose of eliminating concrete that has no carrying
effect.
• By adapting the geometry of the ball and the mesh width, an
optimized concrete construction is obtained, with simultaneous
maximum utility of both moment and shear zones.
• High density polyethylene hollow spheres replace the in- effective
concrete in the centre of the slab, thus decreasing the dead weight
and increasing the efficiency of the floor

5. TYPES OF BUBBLE DECK
• Type A- Filigree Elements
• Type B- Reinforcement Modules
• Type C- Finished Planks

6. Filigree Elements
O It is a combination of constructed and
unconstructed elements. A 60 mm
thick concrete layer that acts as both
the formwork and part of the finished
depth is precast and brought on site
with the bubbles and steel
reinforcement unattached. The
bubbles are then supported by
temporary stands on top of the
precast layer and held in place by a
honeycomb of interconnected steel
mesh. Additional steel may be
inserted according to the
reinforcement requirements of the
design. The full depth of the slab is
reached by common concreting
techniques and finished as necessary.

7. Reinforcement Modules
O A reinforcement module one
which consists of a pre-
assembled sandwich of
steel mesh and plastic
bubbles, or "bubble lattice“.
O These components are
brought to the site, laid on
traditional formwork,
connected with any
additional reinforcement,
and then concreted in place
by traditional methods.

8. Finished Planks
O Is a shop-fabricated
module that includes the
plastic spheres,
reinforcement mesh and
concrete in its finished
form.
O The module is
manufactured to the final
depth in the form of a
plank and is delivered on
site

14. ELEMENTS
Horizontal upper concrete part.
Horizontal lower concrete part.
Vertical ribs.
First construct bottom concrete part and then upper concrete
part.

15. Effects
 Weight reduction- The basic effect of the bubbles is
the weight reduction of the deck. The dead load of
the Bubble Deck is 1/3 lesser than a solid deck with
the same thickness – and that without effecting the
bending strength and the deflection behavior of the
deck.

17. Structural
 Less weight
 Increased strength
 No need of beams
 Only few columns required
 Larger span
 Less foundation depth
 Less excavation required.

18. CONSTRUCTION
• Easy incorporation of
ducts and pipes into slab
• Less work on construction
site
• These slabs and column
system acts as an elastic
membrane which transfer
horizontal forces to stiff
vertical structures which is
used for Earthquake
resistant designs.
FIRE RESISTANT
In an intense, prolonged
fire, the ball would melt
and eventually char
without significant or
detectable effect Balls
simply carbonize. No toxic
gasses will be released.

19. Environmental Advantages
• Less material and energy consumption
• Reducing CO2 emission up to 40 kg/m2
• 1kg of plastic replaces 100kg of concrete
• Every component can be recycled

20. Economic Advantage
• Economy
• Savings in materials
• Transportation costs reduced
• Faster construction time
• Buildings can be more flexible and easy in installations.

22. CONCLUSIONS
 The bubble deck technology is environmentally green and sustainable; avoiding
the cement production allows reducing global Co2 emissions.
 In comparative of conventional slab the volume of concrete in bubble deck
(continuous) are less required, that is 25% approximate.
 Cost and time saving by using bubbles in the slab like weight of slab, concrete
volume indirectly load on the beam and walls also decrease/ less so that building
foundations can be designed for smaller dead loads.
