· For recycled concrete aggregate, it might be regarded as an aggregate between natural and lightweight aggregate. Thus, the research work on the behaviour of RAC beams subjected to shear is of great significance. In China, Lan (2005) carried out the first experimental work on the shear performance of RAC beams. In his test, the beams were prepared with stirrups and three RCA .

Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions.
