Abstract: In case of an explosion event, secondary risks arise from component debris ejected from affected structures. In particular, concrete and masonry wall elements pose a potential hazard due to their high fragmentation when exposed to blast load. Adequate structural design and blast mitigation measures are crucial to ensure the integrity and robustness of the structure. A polyurea-based coating can increase the strength of the load-bearing structure and reduce the amount and velocity of debris. The general effectiveness of this approach has already been widely demonstrated. However, comprehensive research for this specific application in terms of blast loading is lacking. The paper investigates the factors that influence the behavior of polyurea-coated concrete walls with both experimental and numerical approaches. Experiments are performed with a shock tube representing a far-field detonation scenario. Additionally, a numerical model is implemented in LS-DYNA considering the dynamic, strain rate-dependent material properties of reinforced concrete and polyurea as well as the adhesive bond of the polyurea–concrete interface. The test results are used to validate the adopted simulation model. By comparing the results to uncoated concrete wall panels for both experiment and simulation, the blast mitigation effect of polyurea coating for concrete wall panels is assessed: the coating proved to be effective in preventing the generation of high-speed ejecta and also in limiting, to some extent, the crack propagation in the concrete panel. The results set a ground for further development of recommendations or guidelines for structural protection using polyurea coating. [ABSTRACT FROM AUTHOR]
