BUBBLE DECK SLAB - EDGE OVER CONVENTIONAL SLAB

Abstract

Bubble Deck slab is a method of virtually eliminating all concrete from the middle of a floor slab, which is not performing any structural function, thereby dramatically reducing structural dead weight. The BubbleDeck is a two-way hollow deck in which High density polyethylene hollow spheres eliminating concrete that has no carrying effect. BubbleDeck slab is an in-situ slab which is created by inserting voids in the form of bubbles which reduces dead weight and is an eco-friendly practice. Plastic waste is non – degradable and its disposal has become a matter of great concern to the environment. Bubbles can be created in various forms using recycled plastic. Recycling of plastic waste is of utmost importance to create an eco-friendly atmosphere.

The aim of this paper is to discuss about various properties of BubbleDeck slab based on the various studies done abroad. Currently, this innovative technology has only been applied to a few hundred of multi-story and residential floor slabs. The paper also gives a brief idea about the different BubbleDeck slabs, their production and procedure for laying out the BubbleDeck concrete slab and advantages over conventional concrete slabs.
