Abstract: Experimental tests on specimens of recycled concrete at early ages are conducted to examine how its basic tensile creep varies with recycled coarse aggregate of different quality, recycled coarse and fine aggregate of different replacement rates, and pre-cleaning of recycled fine aggregate. Test results show that this creep increases with the replacement rate but decreases with the volume fraction of natural aggregate, and that pre-cleaning of recycled fine aggregate is an effective way to reduce the creep by 4.1% ~ 7.9%. Our calculations and analysis demonstrate that by introducing parameters representing the volume of natural aggregate and replacement rate of recycled fine aggregate, a model for prediction of the basic tensile creep of recycled concrete at early ages can be constructed through certain modification on the M-Burgers model that is limited to the basic tensile creep prediction of normal concrete.
