Specific Fracture

This paper deals about behavior of fiber reinforced cement composite in dependence on the casting direction. Almost fifty concrete prisms of size 400 x 100 x 100 mm were cast; half of these were fiber reinforced concrete (FRC) and the other half was ultra-high performance fiber reinforced concrete (UHPFRC). Approximately one half of both mixtures was cast in horizontal direction and the other half vertically. It was found that the specific fracture energy of horizontally cast prisms was approximately 4,5 times larger for both materials than the vertically cast ones. Ultimate loads of FRC were very similar for both casting directions. Peak loads of the horizontally cast UHPFRC prisms were approximately 3 times larger than the vertically cast ones. This research confirmed that there is significant influence of the casting direction on the fiber reinforced concrete characteristics.
