| Abstract: | Based on the investigation on the workability of fiber reinforced self-compacted concrete (FRSCC), this paper analysed the influence of the types of fibers, including steel fiber, polypropylene fiber and hybrid fiber, on the compressive strength and flexural toughness according to different international guidelines. The effect of hybrid fiber on the toughness and failure patterns of self-compacted concrete is verified by the results of investigation. |
| Keywords: | steel fiber PP fiber hybrid fiber self-compacted concrete flexural toughness failure pattern |
