Abstract
Slab is the most important structural member of any building structure and also one of the largest member consuming concrete.Thus, the alternative biaxial hollow slab system known as bubble deck slab had been introduced as one of the effective slab systemsthat improves building design and performance while reduce the self-weight by eliminating concrete part in the middle ofconventional slab which does not contribute to the structural performance. The effective hollow slab systems that dramaticallyreduce the slab weight by 30-50%. Moreover, concrete usage is reduced as 1 kg of recycled plastic replaces 100 kg of concrete. Thenew prefabricated construction technology using bubble deck slab is recently applied in many industrial projects in the world. Ithas many advantages as compared to conventional reinforced concrete slab such as lower total cost, reduced material use,enhanced structural efficiency, decreased construction time, and is a green. The aim of this paper is to discuss the significance andvarious properties of bubble deck slab against conventional reinforced concrete slab based on various studies and researches thathad been done.
