Experimental investigation of polyurethane-coated HPFRC panels under direct contact blast
Original language description
High-performance fibre-reinforced concrete (HPFRC) exhibits exceptional resistance todynamic loading, making it a promising material for structures exposed to blast or impact events.However, when used to produce thin panels, it can experience scabbing under extreme loads. Toaddress this and enhance the blast resistance, this study explores the application of a polyurethane (PU)coating to the HPFRC panels. Coated and uncoated panels undergo direct contact blast testing andvarious factors, such as crater area, rear fragment formation, cracking, and residual flexural strength,are analysed. Our study indicates that applying a PU coating to the panels could effectively preventscabbing and mitigate the risk of complete perforation, while it appears that it results in the panelabsorbing more energy during blast, leading to increased damage and a subsequent decrease in residualflexural strength compared to bare panels.
