The four-point bending behaviour of composite sandwich panels made of corrugated steel faces and foamed concrete (FC) cores with a density of 700 kg/m3 is reported. Plain FC (PFC) core and fibre-reinforced FC (FRFC) core, reinforced with an alkaline-treated natural fibre (henequen fibre) at a volume fraction of 1%, were used. FRFC core reinforced with polypropylene fibre was also used as a reference. The results showed that panels with FRFC cores exhibited greater initial failure load, maximum load and energy absorption when compared to the PFC cored panels, which was associated with the enhancements of ductility and toughness of the FRFC cores produced by the fibres. Several energy absorbing mechanisms were observed in the panels, includin...
