Microstructure recovery plays an important role in restoring the performance of concrete damaged by fire. This research applied X-ray CT and image analysis techniques to non-destructively examine the internal microstructure of high-strength concrete in order to clarify the effects of heating and re-curing on microstructure characteristics. Heating caused an increase in total pore space due to an increase in connectivity caused by the formation of cracks in the mortar-aggregate interface and bridging cracks. Water re-curing, however, was effective in recovering microstructure through the reduction in connected pore space, with most recovery occurring within 7 days.
