Dec 15, 2016  This paper presented an experimental study on the creep behaviour of recycled aggregate concrete (RAC) with recycled coarse aggregates (RCA) obtained from different concrete sources. Considered parameter included the water-to-cement ratio for the RAC (w/c) of 0.3, 0.45, and 0.6 and that for the source concrete (w or /c or) of 0.3, 0.45, and 0.6.
