In this paper, the concepts of linear elastic fracture mechanics are summarized. It is shown that a single fracture parameter, such as the critical stress intensity factor, cannot be simply applied to quasi-brittle material like concrete. A two-parameter fractuer model is presented. The two parameters can be calculated from an (ASTM-type) notched-beam test. This model accurately predicts fracture toughness, as well as split cylinder strength and modulus of rupture strength of high-strength concrete.
