Randomized trial evaluates geopolymer stabilization methods for sulfate-rich soils, indicating enhanced strength and durability.

Key Points

This study aims to explore innovative geopolymer methods for stabilizing sulfate-rich soils and assess their effectiveness compared to traditional methods.
Applied geopolymer stabilization with GGBS, MK, and FA for sulfate-rich soils with 284,400 ppm sulfate content.
Conducted unconfined compressive strength tests and durability assessments on samples cured for 28 days.
Utilized deep soil mixing (DSM) for preparation and performed SEM, EDS, and FT-IR for microstructural and chemical analysis.
Achieved maximum strength increase of 64.13% in MK100 specimen after 28 days of curing.
Combined use of GGBS and MK resulted in average 38% strength increase, while GGBS and FA caused average 22% strength decrease.
Identified significant microstructural changes through SEM and chemical compositions via EDS and FT-IR analyses.
