Abstract: Bubble deck slab can be achieved by reducing the weight of the slab by eliminating unwanted concrete which is not playing the role in the interlocking of aggregate for shear resistance and the remaining concrete act as the compression block for flexural resistance. Further, the larger spans with less design loads to the columns and footings without compromising flexural strength of the slab with minimum deflections are possible with this renowned technology. This paper presents a comprehensive review of the structural behaviour of bubble deck slab. The analytical and experimental studies on bubble deck slabs under general loading to know the structural behaviour has been presented in this article. The structural behaviour 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 slabs are more economical and efficient with respect to structural integrity while comparing with conventional slabs.
