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. Housing all over the world majorly comprises of concrete structures. They provide isolation and thermal comfort to the occupants. Majority of the concrete structures have flooring/roofing of thick concrete to bear the design loads. . A bubble deck slab, also known as voided biaxial slab, is one of the latest innovations in the construction sector. A bubble deck slab is constructed by placing high density polyethylene hollow spheres in between the steel reinforcement placed on its top and bottom. Generating the gaps leads to a 30 to 50% lighter slab which reduces the loads on the columns, walls and foundations, and of course of the entire building. . The advantages of the bubble deck slab are less energy consumption, less emission - exhaust gases from production and transport, especially CO2. Bubble Deck is a method of eliminating concrete from the conventional flat slab which does not perform any structural function, hence reducing structural dead weight and increasing efficiency of the floor. . In the Bubble deck technology reduce the concrete volume by replacing plastic balls which are locally available. This system can be used for roof and ground floor slabs also it does not require beams and column heads. This technology reduces cost of construction. . It is a revolutionary method which virtually eliminates all concrete from the middle portion of a floor slab. The structural dead weight is reduced due to the non-performance of any structural function by the middle portion of the slab. High density polypropylene spherical balls replace the in-effective concrete in the center of the slab. Voids in the middle of the slab provide thermal insulation and also leads to 30 to 50% lighter slab. Bubble deck slab allows longer spans between columns supports. In this paper, flexural strength of the slab was determined by two-point load test. A new solution to reduce the weight of concrete structures and increase the spans of two-way reinforced concrete slab systems was developed in the 1990s in Europe and is gaining popularity and acceptance worldwide. . The structural behavior of the bubble deck slab has been assessed through flexural strength, shear strength, punching shear, anchoring, crack pattern, fire resistance, creep, crack pattern. From the review of literature, it has been concluded that the bubble deck slab are more economical and efficient with respect to structural integrity while comparing with conventional slab.
