要旨 Re-curing of fire-damaged concrete can restore structural performance without removal and casting operations, reducing waste generation and resource consumption. In this research, the effect of water re-curing on the recovery of damage due to fire was investigated. Recovery of pore structure and crack self-healing were observed and attributed to both the rehydration of dehydrated cement as well as the hydration of unhydrated cement particles. Finally, in order to bridge the gap between mortar and concrete, damage and self-healing around aggregates was discussed.
