Durability and Microstructural Evolution of Class C/Class F Fly Ash Geopolymer Mortars with Different Ash-to-Sand Ratios Under Combined Freeze–Thaw and MgSO₄

This study investigates the durability of Class C/Class F fly ash geopolymer mortars with varying ash-to-sand ratios under freeze–thaw cycles, MgSO₄ exposure, and their combined action. The results showed that geopolymer specimens with ash-to-sand ratios of 1:1.4 and 1:1.6 exhibited excel...
