Mechanical Properties of Silty Clay Stabilized with Sisal Fibers and Municipal Solid Waste Incinerator Bottom Ash Subjected to Freeze–Thaw–Dry–Wet Cycles
In cold and arid regions, climate change has exerted significant impacts on the mechanical properties of soils. Specifically, the interplay between freeze–thaw (F-T) and dry–wet (D-W) cycles profoundly influences the long-term stability of geotechnical engineering. Therefore, this study focused on mitigating the adve...

Durability and leachability of solidified lead-zinc red clay under acidic wet-dry cycles
Soil heavy metal (HM) contamination is a widespread and serious environmental challenge. Even after treatment, contaminated soil may still pose a risk of secondary metal release under complex environmental conditions. In this study, a novel solidifying agent, a diatomaceous earth–fly ash-based geopolymer (D-FA), wa...

Strength and Durability of Natural Fine-Grained Soil Stabilized with Fly Ash–Based Geopolymer: Effects of Sulfate Attack and Freeze–Thaw Cycles
Problematic fine-grained soils exhibit low strength and inadequate durability, highlighting the need for sustainable stabilization using eco-friendly binders. This study examined the strength development and durability of a natural CH soil (NSs) stabilized with fly ash (FA) based geopolymer exposed to sulfate attack an...

Sustainable Stabilization of Lateritic Soil Using Rice Husk Ash-derived Nano-silica: Effects on Index Properties and Compaction Characteristics
The growing need for sustainable materials in geotechnical engineering has encouraged the use of agricultural waste-derived nanomaterials for soil improvement. This study investigated the potential of nano-silica synthesised from rice husk ash (RHA) to improve the index properties and compaction characteristics of late...

Sustainable stabilization of lean clay using fly ash, silica fume and GGBS: Effects on unconfined compressive strength and California bearing ratio
Lean clay soils are considered among the most problematic soil types in civil engineering due to their low shear strength and high compressibility, which necessitate remediation to limit post-construction settlement and ensure adequate bearing capacity. Chemical stabilization is widely adopted for improving such weak g...

Freeze–Thaw Characteristics of Pb(II)-Contaminated Soil Stabilized Using NaOH- and Na 2 SiO 3 -Activated Geopolymer
Lead [Pb(II)] contamination poses a significant environmental concern due to its detrimental effects on soil physicochemical (i.e., physical and chemical) properties and structural stability. This issue is further exacerbated by freeze–thaw (F-T) cycles, which accelerate the migration and redistribution of heavy me...
