Recycled concrete which is applied in practical engineering has been suffering much damage from all aspects.The buildings in the Three-North Regions are suffering from damage from freeze-thaw erosion and sulfate erosion,the safety and durability are seriously affected,and the service life is short.Combined with the research status of resistance of frost-shaw durability at home and abroad,the failure mechanism and influencing factors of mechanical properties of recycled concrete after freeze-thaw and sulfate freeze-thaw cycles are analyzed respectively,and the resistance improvement measures to frost-thaw durability of recycled concrete are summarized.Finally,suggestions on the research direction of recycled concrete are put forward,which aim at the practical engineering application of recycled aggregate concrete in freeze-thaw areas.
