n this paper experimental and numerical determination of the mixed-mode fracture toughness of cementitious composite is described. As a part of experimental efforts, mixed-mode fracture tests were performed using semi-circular specimen containing an edge crack under three-point-bending (SCB) specimen which by varying the direction of crack to load, mixed-mode fracture data were obtained. Finite element analyses (FEA) were also carried out on SCB specimens. The main objective of this study was to determine the fracture toughness KC and critical strain energy release rate GC under mixed-mode loading conditions. Fracture toughness obtained at different mixed mode loading conditions were also discussed.
