What is Geopolymer Strength Under Heat Exposure about?

This study investigated the effects of elevated temperatures on geopolymer composites and geopolymer/aggregate composites. Geopolymer samples exhibited strength increases of around 53% after exposure to temperatures up to 800°C, while geopolymer/aggregate composites decreased in strength by up to 65% after the same exposure. Dilatometry tests showed that aggregates expanded by 1.5-2.5% at 800°C, while the geopolymer matrix contracted, causing incompatibility and strength loss in the composites. The results
