In　order　to　expand　the　application　range　of　recycled　concrete　and　fully　realize　its　economic　and　low-carbon　benefits,　the　application　of　composite　recycled　concrete　and　its　derivative　structures　were　analyzed　and　sorted,　and　the　characteristics　of　recycled　aggregate　and　recycled　concrete　were　summarized.　The　problems　of　composite　recycled　concrete　were　analyzed　and　the　future　research　was　prospected.　The　results　show　that　recycled　concrete　has　the　characteristics　of　low　strength　and　small　elastic　modulus　compared　with　ordinary　concrete.　It　is　often　difficult　to　meet　the　mechanical　properties　and　functional　requirements　of　various　parts　of　the　structure　by　relying　on　recycled　concrete　itself.　Through　the　forms　of　composite　recycled　concrete,　recycled　concrete　is　combined　with　other　concrete　in　the　form　of　components　and　structures,　or　the　recycled　aggregate　is　combined　with　other　aggregates.　Concrete　that　meets　the　performance　requirements　can　be　placed　on　specific　parts,　which　is　not　only　environmentally　friendly　but　also　can　give　full　play　to　the　respective　advantages.　The　interfacial　shear　strength　between　different　concretes　has　an　important　influence　on　the　performance　of　composite　recycled　concrete　structures.　The　shear　strength　is　affected　by　many　factors　such　as　interfacial　roughness,　binder　and　concrete　strength.　Increasing　the　interfacial　roughness　can　effectively　improve　the　integrity　and　safety　of　composite　recycled　concrete　and　its　derivative　structures.　The　combinations　of　composite　recycled　concrete　with　BIM,　3D　printing,　prefabricated　buildings　and　smart　materials　can　achieve　green　construction　while　ensuring　structural　performance.　©　2023,　Editorial　Department　of　Journal　of　Architecture　and　Civil　Engineering.　All　rights　reserved.
