摘要：
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.
