This paper describes flexural behavior of fiber reinforced lightweight self-consolidating concrete (FRLWSCC) beams made of slag aggregates in combination three different types of fibers such as: High-Density Poly Ethylene (HDPE), Crumb Rubber (CR) and Polyvinyl Alcohol (PVA). The performance of FRLWSCC beams compared to their lightweight self-consolidating concrete (LWSCC) counterparts is described based on load-deformation responses, stress-strain developments, crack characterization, failure modes, ductility and energy absorbing capacity. All beams have shown flexural failure the bending region. FRLWSCC flexural beams have shown higher ultimate flexural capacity, higher deflection, ductility and higher energy absorption capacity with development of more number of cracks with smaller crack width compared to their LWSCC counterparts.
