Abstract: This study investigates the effect of silica moduli (SiO2/Na2O ratio) of alkaline activators on the degradation mechanisms of fly ash–based geopolymer (FAG) mortars that are exposed to elevated temperatures of up to 1,000°C. ...

Abstract: In this study, we investigated the degradation process of metakaolin-based geopolymers exposed to high temperatures up to 1,000°C. The changes in mechanical properties, microstructure, and phase assemblage of the samples ...
