Bubble Deck Slab

What is Bubble Deck Slab ?

Bubble deck slab is a method of eleminating all the concrete from middle in-effective portion of slab which is not performing any structural function & reduce the dead load of structure.

Bubble Deck Slab Method:

In the slab, middle portion which is not effective replaces concrete by high density polyethylene hollow spheres. 

Why bubble deck slab ?

• No need of beam.
• Longer spans.
• No compromise for strength and serviceability.
• Pre-fabricated and cast in situ.

Structural Advantage:

• Less weight.
• No need of beams.
• Freedom for choice of shape.
• Larger span.
• Few columns are required.
• Increased strength.
• Less excavation.

Engineering Advantages:

• High resistance against explosion.
• These slab and column system acts as a elastic membrane which transfer horizontal force to stiff vertical structure which is used for earthquake resistant design.

Construction Advantage:

• Light weight & required less equipment.
• Does not require heavy job on site work.
• Reduce foundation size.

Economically Advantage:

• Save material.
• Transportation cost reduced.
• Faster construction time.
• Building can be more flexible & easy in installation.
• Lower workforce. 
• No carpentry.

Environmental Advantages:

• Reducing CO2 emission.
• Less energy consumption.
• 1Kg of plastic replaces 100Kg of concrete.
• Each & every component can be recycled.

Future Uses:

• This method can be used for constructing of scrapper.
• Used for constructing parking deck as less number of columns required.
• Pedestrian bridge deck.
