The　application　of　recycled　concrete　structure　is　in　line　with　the　utilization　of　construction　waste　resources　and　the　sustainable　development　of　building　materials.　It　has　received　attention　from　academic　and　engineering　circles　at　home　and　abroad.　The　long-term　working　characteristic　of　recycled　concrete　structures　is　an　important　aspect　in　the　research　of　recycled　concrete,　among　which　the　freezing　and　thawing　resistance,　carbonation　resistance,　chloride-permeation　resistance,　creep　of　recycled　concrete,　steel　corrosion　and　rust　cracking　in　recycled　concrete,　corroded　steel　and　recycled　concrete　bonding　properties,　and　long-term　performance　of　recycled　concrete　components　are　essential　components　to　determine　the　long-term　working　performance　of　recycled　concrete　structures.　The　above-mentioned　qualities　of　recycled　concrete　structures　are　studied　in　this　paper,　which　is　summarized　as　follows:　1)　Progress　has　been　made　on　the　long-term　working　characteristic　of　recycled　concrete　structures,　and　some　valuable　conclusions　have　been　drawn.　However,　some　of　the　research　conclusions　are　not　completely　consistent　or　even　mutually　exclusive,　which　might　be　attributed　to　the　difference　in　recycled　aggregate,　mix　design,　and　test　methods.　Therefore,　further　research　is　still　needed.　2)　Most　of　the　research　is　mainly　based　on　medium　and　low-strength　recycled　concrete,　involving　less　on　high-strength　recycled　concrete.　More　research　on　the　long-term　working　characteristic　of　high-strength　recycled　concrete　should　be　conducted　along　with　the　promotion　of　high-strength　steel　bars,　so　that　recycled　concrete　and　steel　bars　can　fully　draw　on　their　respective　advantages　and　waste　can　be　avoided.　3)　There　are　many　macro　researches　yet　few　micro　studies,　so　research　on　micro　study　should　be　enhanced.　4)　Compared　with　the　research　results　of　long-term　working　characteristic　of　recycled　concrete　materials,　the　research　on　recycled　concrete　component　and　structural　parts　is　relatively　scarce,　and　subsequent　research　on　components　or　structures　should　be　carried　out.　5)　Long-term　working　characteristic　of　recycled　concrete　studies　are　mostly　single　factor　studies,　while　engineering　is　mostly　multi-factor　coupling.　Multi-factor　coupling　research　can　be　carried　out　in　the　future　in　order　to　combine　theory　with　practice.　It　is　expected　that　this　paper　is　able　to　provide　ideas　and　directions　for　the　study　of　the　long-term　working　characteristic　of　recycled　concrete,　and　provide　statistical　and　theoretical　support　for　the　promotion　and　application　of　recycled　concrete.　©　2019,　Editorial　Board　of　Journal　of　Harbin　Institute　of　Technology.　All　right　reserved.
