The most crucial component of any building structure that uses a lot of concrete is the slab. With the help of the ground-breaking building technique known as Bubble Deck, the amount of structurally futile concrete in the middle of a floor slab between columns is almost eliminated. This significantly reduces structural dead weight. The direct method of connecting air and steel is the basis of the unique approach used in Bubble Deck. Plastic balls are used to replace the concrete in the centre of a typical slab, which does not improve its structural performance. The result is a hollow, flat slab that spans in two directions. On the other hand, a conventional slab or normal slab is any slab that is supported by beams and columns. In these varieties, the slab has a short thickness while the beam has a significant depth. Following the columns, the load is passed to the load-bearing beams. Comparatively speaking, this needs more formwork than the Bubble Deck slab. The numerous studies on bubble deck and conventional slab systems were covered in this study. The specified aims must be realized through documentation effort and theoretical analysis of all the works on bubble deck and conventional slab concept produced by various writers. The concrete in the centre of the bubble deck slab was designed and built using hollow plastic bubbles to eliminate the concrete that serves no structural purpose and to reduce the weight of the slab itself. Therefore, compared to a normal concrete slab, the self-weight of a bubble deck slab can be lowered by around 30% to 50%, which can lessen the loads placed on columns, walls, and foundations. Finally, using a bubble deck slab has numerous advantages over using a traditional concrete slab, which include: better structural performance, lower materials and labor costs, quicker building times, and environmental friendliness. Additionally, it was found that the deflection of a bubble deck is 5.88% greater than that of a standard solid slab since the hollow component reduces stiffness. The shear resistance of a slab made of bubble deck material is 0.6 times more than a standard solid slab of equal thickness. However, by adding vertical reinforcement, the necessary resistance can be achieved.
