A broad experimental and analytical effort using fracture mechanics as the prime tool was conducted to investigate and improve the understanding of the mixed-mode fracture behavior of a mortar. 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, mode-I, mixed-mode and mode-II fracture data were obtained. Finite element analyses were also carried out on SCB specimens. The main objective of this study was to determine the fracture toughness and strain energy release rate under mixed-mode loading conditions. Fracture toughness obtained at different mixed mode loading conditions were also discussed.
