Performance of geopolymer concrete composed of fly ash after exposure to elevated temperatures

•The temperature performance of Fly Ash alkali-activated concretes was evaluated.•The residual strength of FA/GBFS concrete at 700°C was 23,71MPa.•The residual strength of FA/OPC and FA/GBFS at 1100°C was 5.5MPa and 15MPa respectively.•New crystalline phases at 1100°C were identified.•These concrete...
