Microstructural investigations of palm oil fuel ash and fly ash based binders in lightweight aggregate foamed geopolymer concrete

•POFA and FA are used to fully replace cement to produce geopolymer concrete.•Micrograph showed OPSFGC of different densities comprises different types of pores.•XRD analysis showed partial dissolution of crystalline phase on OPSFGC over time.•FTIR analysis showed presence of amorphous aluminosilica...
