When coarse aggregate is made out of concrete waste at demolishing concrete structure, in many cases, fine aggregate with small particle diameters is also made at the same time. Therefore, it is a effective use of concrete waste that fine aggregate is used as well as coarse aggregate. However the material properties of recycled concrete are varied by the blend proportion of fine and coarse aggregate. This blend proportion influences the mechanical performance of structural members made of recycled aggregate concrete. The recycled aggregate concrete composed of 100% recycled fine and coarse aggregate is considered to have the worst material properties. This paper reports on the experiments on the flexural, shear, and bond failure of RC beams made of the recycled aggregate concrete composed of 100% recycled fine and coarse aggregate, and examines such concrete's capabilities as appropriate material for a seismic performance of RC frames.
