Abstract:A summary of the results of an experimental program to investigate the structural behavior of composite sandwich beams having polymer concrete (PC) on the top and bottom facings is presented. The possible application of PC as a facing material is of interest since it may provide an effective use for the material. A total of 18 different cross-sectional configurations were investigated. Polyester-based PC facings were used in conjunction with three separate core materials: sand-lightweight portland cement concrete, expanded polystyrene foam, and rigid polyurethane foam. Various combinations of core and facing thicknesses were used. Load-deflection responses, strain and stress distributions, modes of failure, and ultimate strengths of the beams were monitored. The experimental results were compared to sandwich beam theory and, in general, compared well. Overall, the results of the study suggest that the application of PC as a facing material holds high potential and warrants further attention.
