REVIEW ON BUBBLE DECK WITH SPHERICAL HOLLOW BALLS

The aim of this paper is to discuss about various significance of Bubble Deck Slab against Conventional Slab based on the various studies. Reinforced concrete slabs are one of the most common components in modern building construction consuming most of the concrete. Due to the sheer amount of concrete required to produce these slabs, the dead weight of them tend to be very large. Heavier structures are less desirable than lighter structures in seismically active regions because a larger dead load for a building increases the magnitude of inertia forces which the structure must resist, as large dead load contributes to higher seismic weight. Bubble Deck is a revolutionary method which was developed in the 1990s in Europe and is gaining popularity and acceptance worldwide. This method virtually eliminates concrete from the middle of the conventional slab, thereby dramatically reducing structural dead weight. Bubble Deck slab uses hollow spherical or elliptical balls made by recycled plastic. Plastic voided slabs are capable of reducing the amount of concrete necessary to construct a building by 30 percent or more. Voids in the middle of a flat slab eliminate up to 35% of a slab's self-weight removing constraints of high dead loads and short spans. This provides a wide range of cost and construction benefits.
