Abstract: Nowadays, several research are concerned with studying the effect of voids in concrete elements specially voided slabs. The concept of voided concrete slabs depends on removing inactive concrete parts without affecting performance of the elements. This can be accomplished by replacing inactive concrete by hollow plastic forms. There are many systems that adopt this concept like cobiax, bubble deck, U-boot, Bee plate, and donut. This research reviews many experimental and numerical studies concerning voided slabs to shed light on their design methods, their advantages and disadvantages, their comparison with other common flooring systems, and finally the possibility of their application in Egypt.
