The low tensile strength of concrete structures requires studying the effects of fibers on the performance of fresh and hardened concretes where finding the right amount of coarse aggregates is a challenge in the concrete industry. This study has addressed the effects of increasing the volumes of wavy steel fibers (0.15, 0.3 and 0.45%) and coarse aggregates (30, 40, 50 and 60%) on fresh concrete parameters and Self-Compacting Concrete (SCC) strength and fracture characteristics. Results have shown that using wavy steel fibers has negative effects on the properties of the fresh SCC because its efficiency and flowability are reduced, and increasing the coarse aggregate volume has positive effects because the rheological properties are improved. On the other hand, increasing the wavy steel fiber volume will improve the compressive strength in concretes containing 50 and 60% coarse aggregates. Only in 60% coarse-aggregate concretes, increasing the fiber volume from 0.15 to 0.45% will slightly reduce the wavy steel fiber reinforced self-compacting concrete (WSFRSCC) tensile strength. Increasing the coarse aggregate volume (30% – 60%) will improve the elasticity modulus of specimens with fixed percent fiber. Comparison of ASTM C 1609, JSCE SF-4 and JG/T 472-2015 methods revealed that the latter could well provide a thorough understanding of the variations of the flexural toughness of the WSFRSCC due to the demarcation of the pre- and post-peak load areas.
