초록

The elastic modulus of recycled aggregate concrete (RAC) can be evaluated by using composite models with experiment. In this study, Hashin's composite model was adapted to evaluate elastic modulus considering physical properties of recycled coarse aggregate (RCA) that mortar is attached. Elastic modulus testes for cement paste, mortar and recycled coarse aggregate concrete were carried out considering W/C and recycled coarse aggregate content rate. As a result, the elastic modulus of RAC was evaluated comparing with both experiment results and the existing estimation formula. Those can be used for further studies as a preliminary data.
