Recycling Rigid Polyurethane and Aluminum Powder Waste in Sustainable Foamed Geopolymer Concrete

This study evaluates the performance of foamed geopolymer concrete (FGC) incorporating rigid polyurethane (PU) waste as a partial sand replacement and aluminum powder (AP, 1%) as a foaming agent. The mixtures were based on metakaolin, fly ash, and silica fume. Fresh and hardened properties were asse...
