Since the composition of vibrated concrete (VC) and self-compacting concrete (SCC) substantially differs, their mechanical properties, including fracture behaviour, might be different as well. Evaluating the fracture properties of heterogeneous materials, such as concrete, is usually done by experimental investigation. Three-point bending tests (3PBT) and wedge-splitting tests (WST), for instance, allow to examine the fracture process and crack propagation, even though these are not standardized methods. This paper compares the results of static 3PBTs and WSTs on notched specimens, made from both concrete types. Considering the ultimate load, fracture toughness and fracture energy, important differences between VC and SCC are observed.
