摘要：

Test data on the residual fracture energy of two significantly different concrete types are presented. About 80 beams of high performance basalt concrete and ordinary gravel concrete have been tested in accordance with the RILEM work of fracture method. The beams are heated at 1°C per minute up to a certain maximum temperature and kept at this temperature for 8 hours before cooling them back to room temperature and testing in three-point bending.
