The　application　scope　of　concrete　material　is　continuously　expanding　because　of　the　excellent　performance　and　wide　selection　of　raw　materials.The　environmental　temperature　of　the　concrete　structures　ranges　from　a　high　temperature　of　about　1000　to　a　low　temperature　of　-165　in　the　cases　of　fire　disaster,　high　latitude　and　extreme　cold　environment,　as　well　as　the　LNG　storage　tank,　etc.Therefore,　it　is　essential　to　fully　understand　the　influence　of　temperature　on　concrete　materials　and　structural　properties　to　guarantee　the　safety　of　engineering　structure　in　different　environments.A　lot　of　research　work　has　been　carried　out　on　the　performance　of　concrete　structures　at　different　temperatures　while　the　relatively　systematic　theoretical　system　and　design　method　have　been　formed.In　this　paper,　the　research　work　of　the　effect　of　high　temperature　on　the　mechanical　properties　of　ordinary　concrete,　steel　fiber　reinforced　concrete　and　steel　rebar　as　well　as　reinforced　concrete　(RC)　components　was　concluded　and　the　research　progress　of　concrete,　steel　rebar　and　RC　components　at　cryogenic　temperature　was　introduced.Then,　the　research　trend　was　pointed　from　five　respects,　namely,　the　high-temperature　properties　of　high-performance　concrete,　fire-resistant　design　methods　of　concrete　structures,　damage　assessment　and　retrofitting　of　fired　concrete　structures,　low-temperature　properties　of　concrete　materials　and　damage　mechanism,　as　well　as　the　behavior　of　RC　structures　subjected　to　cryogenic　temperature.　©　2021,　Editorial　Office　of　China　Civil　Engineering　Journal.　All　right　reserved.
