Experimental research on the bearing capacity of polyurethane foam sandwich concrete wall-board

In order to study the bearing capacity of polyurethane foam sandwich concrete wall-board, 6 bending specimens and 3 axial compression specimens were designed. According to the experiment, the failure patterns, loading-displacement curves and the stress-strain curves of the specimens were obtained. The results show that polyurethane foam sandwich concrete wall-board average strain of bending normal cross-section does not conform to the plane cross assumption, its failure pattern belongs to the brittle failure; it has a good overall work performance. All of this may be helped for the science research and engineering applications.
