Size-effect sensitivity - Three point bending test versus wedge splitting test

Abstract Fracture mechanics testing of cementitious (concrete) materials is still carried out by a three-point bending (3PB) procedure. Based on a series of advantages compared to 3PB, however, the wedge splitting test (WST) has become more and more widespread. Within this paper the results of extensive investigations concerning the efficiency of WS tests compared to 3PB tests are presented and discussed.
