Abstract
Crumb Rubber Concrete (CRC) has quickly become a hot topic of research for civil engineering as CRC has been proven to exhibit better energy absorption, ductility and impact resistance compared to Conventional Concrete (CC). One possible residential application of CRC is CRC composite slabs, where the bond characteristics between steel profiled sheeting and concrete is one of the key influencing factors that governs the member capacity under shear and/or flexural loads. The current standard design methods of composite slabs are heavily dependent on the results of full-scale bending tests, which are expensive and time-consuming. In this paper, small-scale testing method was attempted to investigate the bond characteristics between re-entrant steel profiled sheeting and CRC. Horizontal push-off tests were conducted with specimens containing CC and CRC. All specimens showed ductile failure mode. The overall performances of CRC specimens in the elemental tests were very close to CC specimens, which indicated the viable substitution of CRC in residential composite slabs
