Abstract

A new creep model of recycled aggregate concrete (RAC) incorporated with coarse recycled aggregates (CRA) and fine recycled aggregates (FRA) is proposed in this paper. The model accounts for the difference in the creep development trend between RAC and natural aggregate concrete (NAC). Experiments are performed to investigate how the incorporation of FRA affects the creep behavior of RAC with the variation in the CRA replacement ratio, and how the incorporation of RA influences the creep development trend. The results show that 1) the incorporation of FRA could reduce the negative effect of CRA on the creep of concrete, and 2) the FRA and CRA influence creep development in concrete. Finally, based on experimental results, current creep models for RAC are modified to account for the aforementioned influences.
