摘要：

Rock-filled concrete (RFC) has become a widely used alternative for massive concrete engineering. Several studies have examined the creep behaviour of normal concrete. However, few studies have focused on the creep behaviour of RFC. In the present study, experimental compressive creep tests and shrinkage tests were performed on specimens with different loading ages with large-sized cylinders under identical laboratory conditions to investigate the creep properties of RFC and self-compacting concrete (SCC). The results showed that the loading age did not significantly influence the creep strain of RFC. Both the creep strain and shrinkage strain of RFC were less than those of SCC. The rock framework in the RFC significantly influenced its creep behaviour, and the creep ratio of RFC was related to the volumetric fraction of SCC. Furthermore, the creep models CEB-FIP and AIC209 were used to analyse the creep behaviour of RFC and SCC. These results can provide a theoretical and experimental basis for further practical engineering applications of RFC. (C) 2018 Elsevier Ltd. All rights reserved.
