In　this　study　the　creep　behaviour　of　self-compacting　concrete,　in　which　slump　flow　was　larger　than　550mm,　containing　fly　ash　were　experimental　investigated　and　compared　with　those　of　vibrated　normal　concrete.　Based　on　the　experimental　results　from　creep　tests　of　sealed　and　unsealed　specimens,　the　effects　of　different　binder　/aggregate　ratios　and　sand　ratios　on　creep　behaviour　of　harden　self-compacting　concrete　was　investigated.　The　results　indicated　that　the　ratio　of　aggregate-to-concrete,　especially　the　content　coarse　aggregate　greatly　influenced　creep　of　SCC.　The　creep　rate　of　SCC　investigated　was　greater　than　that　of　normal　concrete　at　early　age　but　decreased　with　age.
