Notes:
In this paper, the basic damage mechanisms and the primary reasons for the propertyfluctuation of recycled aggregate concrete are investigated experimentally. By a comprehensiveliterature study and systematic laboratory tests, the interactions between the old and the new interfacesin recycled aggregate concrete are analyzed. In particular, the damage initiation and evolutionmechanisms on the old and the new interfaces are studied in details. The essential factors affecting thefluctuation and its extent are investigated from the point of view of material sciences. The presentresults imply that the qualitative and quantitative changes of the old and the new interfaces during theloading process induce a notable fluctuation of the mechanical and the physical properties of recycledaggregate concrete. To reduce the fluctuation and improve the mechanical properties of the recycledaggregate concrete, effective controlling and processing measures are suggested and discussed
