The effects of its components on fracture behavior of composite materials has been a major research topic for many times. In this study, the fracture parameters of concrete, GF which were adopted in fictitious crack model, were introduced for the purpose of evaluating the properties of fracture behavior of concrete with the maximum coarse aggregate size and the compressive strength of concrete varied. Also, two test methods, three point bend test and wedge tension test, were used to evaluate the effect of Gmax on its fracture. The fracture energy are calculated from the load-displacement curves obtained by the three point bend test and wedge tension test.
