摘要：

Effects of crusher dust content in aggregate on properties of fresh and hardened concrete are not very well known. On the other hand, it is known that short discrete fibers delay the propagation of microcracks and improve some properties of concrete. In this research, the effect of crusher dust replacement levels of fine aggregate and hooked-end steel fibers with different aspect ratios and different volumes on some properties of concrete was investigated. All mixes were tested for compressive and splitting tensile strength, water penetration, flexural toughness energy and impact energy. Relations such as compressive strength/splitting tensile strength/water penetration depth/flexural toughness energy/impact energy-dust replacement level-fiber reinforcement index were also determined.
