However, the cube compressive strength with various SFs dosages is still acceptable since they are higher than the designed strength of 25 N/mm2 at 28-days. Besides that, it proof that the higher aspect ratio (i.e. l/d = 80) may /induce lower compressive strength but increase in toughness and peak strain of SFRC which lead to better crack control and energy absorption (Wang et al. 2010).
