Abstract

This paper reports on the influence of coarse aggregate on the fracture properties of concrete subjected to high temperatures up to 800℃. The fracture properties were evaluated based on tension-softening curves which were determined by polylinear approximation through inverse analysis of load versus crack mouth opening displacement (CMOD) curves, obtained from wedge-splitting tests using a dedicated analysis program. The follow conclusions were found in this study: The initial cohesive stress of mortar was higher than that of concrete. And the fracture energy of concrete was higher than that of mortar.
