Abstract

Present study involves the experimental analysis of spherically voided biaxial slabs. The intention was to eliminate the unused concrete in massive slab constructions. Three voided slab specimens (2900 mm × 2900 mm × 100 mm) were cast. The voids were created by introducing spherical-shaped high-density poly propylene void formers in between the compression and tension layers of the slab. The parameter varied was the spacing of the void formers, which were kept as 20, 30 and 50 mm. The corresponding reduction in volume of concrete for the above-mentioned spacing was 22.7, 18.4 and 12.21%, respectively. The slabs were subjected to area loading instead of regular five-point loading. Analytical calculation for the ultimate load carrying capacity was carried out similar to biaxial solid slab. Comparison of load deflection behaviour showed that void spacing between 20 and 30 mm may be provided to satisfy both strength and serviceability criteria. The percentage reduction in volume of concrete was found to be directly proportional to percentage reduction in cost of construction.
