Abstract

•The fly ash source has a significant effect on fly ash-based geopolymer concrete compressive strength.•The particle size distribution (PSD) has a direct effect on the compressive strength.•The fly ash source has a significant effect on fly ash-based geopolymer concrete microstructure.•The finer the fly ash particle size distribution, the more significantly permeable void ratio was reduced.•Fewer microcracks were observed when finer fly ash was used.
