The objective of this experimental investigation was to clarify the effect of coarse aggregate on fracture behavior of high-strength concrete in mixed-mode loading 'conditions. Energy absorption in mixed-mode fracture was evaluated by the total work of fracture calculated by analysing the load-load point displacement curve. Mixed-mode loading, conditions were set for a wide range which consists of shear/compression and shear/tension. In case of shear/tension mode, energy absorption was decreased with.increasing the factor of tensile force, and major factor effecting the cracking is the interface property of aggregate and mortar. In case of shear/compression mode, energy absorption was increased with increasing the factor of compressive force. Aggregate property was the important factor to improving the toughness of high-strength concrete specimen.
