“…Despite the fact that the spherical form is the common shape for the void formers, however, according to Jamal & Jolly, (2017) and Mohan & Sukumaran, (2018), the studies have shown that bubble deck slab with elliptical balls has a better load carrying capacity and lighter in weight compared to the spherical balls. Nonetheless, the statement of elliptical void formers having better load carrying capacity is contradicted with the study done by Habeeb et al, (2021), the finding shows that the bubble deck slab with spherical balls has better load-bearing capacity than those with elliptical balls with the same ratio of bubble diameter to slab thickness.…”

The conventional floor slab has few drawbacks of giving little structural support and posing a large amount of self-weight to a building. Therefore, bubble deck slab system is introduced to tackle these limitations. This paper aims to provide a comprehensive review of the bubble deck slab system on its design and performance. A systematic literature review was conducted in this paper based on the selected journal and articles through the database search engine. The findings will better understand the feasibility of the bubble deck slab system and its potential as a viable replacement for the conventional floor slabs.

“…Additionally, while the spherical shape is commonly used for void formers in bubble deck slabs, recent studies by Jasna et al, [14] have indicated that elliptical balls offer superior load-carrying capacity and reduced weight compared to spherical balls. However, it is essential to note that this claim contradicts the findings of a study by Maha et al, [15]. As reported by Maha et al, [15], bubble deck slabs with spherical balls exhibit superior load-bearing capacity compared to those employing elliptical balls, with an approximate advantage of 3.7% and 9.7%, respectively, when maintaining an equal ratio of bubble diameter to slab thickness.…”

Slabs are vital for supporting loads and forming the foundation for structures' floors and roofs, classified as one-way or two-way based on deflection characteristics. A recent innovation in construction, the Reinforced Bubble Deck Concrete (RBDC) slab, integrates spherical or elliptical hollow bubbles within the slab for reinforcement, reducing concrete usage without compromising structural integrity. This unconventional approach diverges from traditional methods. The manuscript thoroughly reviews existing literature on the design and testing of Reinforced Bubble Deck Concrete slabs, aiming to explore their diverse characteristics as observed in international research studies. Findings demonstrate that these slabs offer a sustainable and cost-effective alternative to traditional floor slabs. Their capacity to reduce weight while maintaining strength suggests they could revolutionize construction practices, potentially replacing conventional floor slabs in various projects.

“…Also, (Singh et al, 2022), (Singh et al, 2021), (Singh et al, 2021) in their studies have presented the parameters, empirical equation along with experimental validation for the shear as well as the flexural design of High strength concrete. (Habeeb et al, 2019), (Habeeb et al, 2021), studied the punching shear in flat slabs made with Lightweight aggregate concrete having compressive strength up to 43 MPa. (Ojha et al, 2021), (Ojha et al, 2020) performed a series of experiments to evaluate the creep and shrinkage properties of high-rise buildings.…”

Las Normas India IS:456-2000 y Europea EC:02-2004 para el diseño de estructuras de hormigón se limitan al hormigón con resistencia a la compresión de 55 MPa y 90 MPa respectivamente. Para definir los parámetros del bloque de tensión y para el diseño de estructuras de hormigón utilizando hormigón de muy alta resistencia (100 MPa a 150MPa) es necesario contar con un comportamiento tensión-deformación bien definido y, especialmente, con los valores experimentales para la deformación en la tensión máxima y la capacidad de deformación última. El presente estudio intenta satisfacer estas necesidades mediante la evaluación experimental del comportamiento a la tensión-deformación de nueve probetas cilíndricas de hormigón no confinado sometidas a una compresión entre 100 MPa y 150 MPa, en una máquina de ensayos a la compresión servo-controlada (controlada por tensión). Los valores de deformación registrados para el esfuerzo máximo del hormigón de 100 MPa y 150 MPa fueron de alrededor de 3.000 y 3.500 micro deformaciones respectivamente. En comparación con el hormigón normal y de alta resistencia, el tramo ascendente de las curvas para el hormigón de muy alta resistencia es mucho más pronunciado y se aproxima a una trayectoria recta, además coinciden la deformación en el esfuerzo máximo y la deformación última, representando un área insignificante de endurecimiento por deformación posterior al pico. El Transformador Diferencial de Variación Lineal (LVDT) y el compresometro mostraron diferentes deformaciones para la misma probeta y carga. Esto demuestra el rol de la relación de la longitud de calibre utilizada en estos dispositivos de medición de tensión
