Fiber-reinforced　polymer　(FRP)　has　been　widely　used　in　civil　engineering　due　to　its　light　weight,　high　strength,　convenient　construction,　and　strong　corrosion　resistance.　One　of　the　important　applications　of　FRP　composites　is　the　concrete-filled　FRP　tube　(CFFT),　which　can　greatly　improve　the　compressive　strength　and　ductility　of　concrete　as　well　as　facilitate　construction.　In　this　article,　the　compressive　performances　of　a　normal　concrete-filled　FRP　tube　(N-CFFT)　column　with　5-hour　curing　time　and　an　ultra-early　strength　concrete-filled　FRP　tube　(UES-CFFT)　column　with　zero　curing　time　were　studied　by　considering　the　characteristics　of　rapid　early　strength　improvement　of　ultra-early　strength　concrete　and　the　confinement　effect　of　the　FRP　tube.　Monotonic　axial　compression　tests　were　carried　out　on　3　empty　FRP　tubes　(FTs)　without　an　internal　filler　and　6　CFFT　(3　N-CFFTs　and　3　UES-CFFTs)　specimens.　All　specimens　were　cylinders　of　200　mm　in　diameter　and　600　mm　in　height,　confined　by　glass　fiber-reinforced　polymer　(GFRP).　Test　results　indicated　that　the　compressive　bearing　capacity　of　the　specimens　increased　significantly　by　adopting　the　ultra-early　strength　concrete　as　the　core　concrete　of　the　CFFT,　although　the　curing　time　was　zero.　It　was　also　shown　that　the　compressive　behavior　of　the　UES-CFFT　specimens　with　zero　curing　time　increased　significantly　than　that　of　the　N-CFFT　specimens　with　5-hour　curing　time　because　the　former　was　able　to　achieve　rapid　strength　enhancement　in　a　very　short　time　than　the　latter.　The　ultimate　compressive　strength　of　UES-CFFT　specimens　with　zero　curing　time　reached　78.3　MPa,　which　was　66.2　and　97.2%　higher　than　that　of　N-CFFT　with　5-hour　curing　time　and　FT　specimens,　respectively.　In　addition,　a　simple　confinement　model　to　predict　the　strength　of　UES-CFFT　with　zero　curing　time　in　ultimate　condition　was　introduced.　Compared　with　the　existing　models,　the　proposed　model　could　predict　the　ultimate　strength　of　UES-CFFT　specimens　with　zero　curing　time　with　better　accuracy.
