The coarse aggregate produced from the construction and demolished waste of masonry structure is called mixed recycled coarse aggregate (MRA), which is mainly composed of concrete recycled coarse aggregate (CRA) and brick recycled coarse aggregate (BRA). The paper presents the results of an experimental and numerical study of concrete composite sandwich panel made with MRA. The composite sandwich panel with MRA (CSPMRA) were tested under axial compression to investigate the influence of concrete mix proportion, thickness of insulation board and added edge frame on the load-displacement curve, load-strain curve, vertical displacement, ultimate bearing capacity and failure mode of CSPMRA. Results of the experimental and finite element analysis (FEA) were compared with the results based on Chinese code, ACI design equation and other empirical equations developed by researchers which might be applicable to predict the ultimate load of sandwich panels. A semi-empirical equation was proposed to better fit the experimental and the FEA results.
