摘要：
Results are given for the fracture energy of concrete preheated to temperatures in the range of 20 degreesC-600 degreesC, then tested at room temperature in three-point bending, for both slowly-cooled specimens and those delivered a thermal shock. Fracture energy measurement techniques are discussed, and comparisons made across previous studies. The results suggest a significant difference between residual and 'hot' capacities, along with a temperature dependence on the ductile-brittle transition.
