Massive　self-compacting　concrete　pumped　in　steel　tube　columns　has　been　used　more　and　more　widely　in　super　high-rise　buildings　and　bridge　engineering　at　present.　The　early-age　expansion　and　shrinkage　performance　of　its　core　mass　concrete　is　an　important　index　to　ensure　the　stress　state　of　triaxial　compression　and　structural　safety.　However,　no　relevant　reports　have　been　found.　In　view　of　the　actual　building　with　the　height　of　265.15　meters,　the　early-age　expansion　and　shrinkage　tests　of　the　massive　self-compacting　concrete　pumped　in　full-scale　columns　with　the　height　of　12.54　m　and　12.24　m　and　diameter　of　1.3　m　and　1.6　m　were　carried　out　by　means　of　strain　gauges　embedded　in　concrete-filled　steel　tubes　(CFSTs).　The　early-age　variation　regularity　of　the　vertical　and　horizontal　expansion　and　shrinkage　strains　for　the　core　concrete　with　the　diameter　of　steel　tube,　development　time,　temperature,　the　pouring　pressure,　expansion　stress,　and　so　on　is　given.　The　calculation　model　of　its　early-age　deformation　strains　is　presented　in　this　paper,　which　is　in　good　agreement　with　the　experimental　results.　It　provides　the　basis　of　experimental　and　theoretical　analyses　for　shrinkage　compensation　of　massive　self-compacting　concrete　pumped　in　steel　tube　columns.
