The Bubble Deck slab is an innovative construction technique that incorporates spherical plastic voids inside concrete slabs to diminish self-weight while preserving structural integrity. This technology reduces the amount of material used by a significant amount by carefully replacing non-structural concrete with voids, which results in cost savings and improved sustainability. The production of bubble deck slabs, their design principles, benefits, drawbacks, and new developments in their use are all covered in this review study. Particular emphasis is placed on their role in modern construction, highlighting their environmental benefits, ease of installation, and structural performance compared to conventional solid slabs. Additionally, the study also highlights critical research areas, including the interaction between voids and reinforcement, the slab's behavior under static and dynamic loading conditions, and its contribution to sustainable building practices. Bubble Deck slabs help make concrete production more sustainable by minimizing the total carbon impact, improving load distribution, and decreasing construction waste. Even with these limitations, recent progress in material science and computational modeling has strengthened their potential as a sustainable and efficient substitute for standard reinforced concrete slabs. The use of Bubble Deck technology is an important advancement in the direction of structural systems that are more efficient in their use of resources and that perform better, as construction practices continue to develop toward more environmentally friendly solutions.
The main purpose of this search is to study the punching shear behavior of fourteen specimens of Reactive Powder Concrete (RPC) two-way flat plate slabs, half of these slabs have been exposed to a high temperature up to 400 C° by using an electric oven. All slabs have dimensions of (400x400x60) mm, with steel reinforcement mesh of (Ø6mm) diameter. Laboratory tests show that there is an increase in the value of First Crack Loading (FCL) and Ultimate Load (UL) by (208, and 216.67) % and a decrease in deflection by (56.85) % due using slab with complete reactive powder relative to a slap made of normal concrete. The use of the (RPC)mixture in layers in slabs gave results close to the slab which consists of full (RPC) this gives the benefit of more than the use of a slab that contains full reactive powder concrete in terms of cost, the increase was in FCL and UL by (130.8, 169.23, 102.7 and 135.135) % and a decrease in the value of deflection by (37.17, 47.64) %. The use of a partial reactive powder mixture also showed good results, and by increasing the dimensions of the RPC area, the results were better. the increase in FCL and UL by (54, 116, and 185) % and (53, 116.67, and 166.67) % and a decrease in value of deflection by (36.12, 42.4, and 50.26) % from reference slab. When slabs are subjected to high temperatures, there may be a decrease in the value of the FCL and UL and an increase in the value of deflection when compared to models not exposed to high temperature. But when compared to the reference slab with the same circumstance showed an increase in the value of the FCL and the rate ranged between (50- 200) % and the UL was the ratio ranged between (51.35-208.1) % and a decrease in the value of the deflection where the ratio ranged (21-46) %
