Research on the permeability characteristics and its various affecting factors of compacted bentonite mixed soil

Puntos clave

• This research aims to understand how various factors affect the permeability of compacted bentonite mixed soil.
• Conducted permeability tests on bentonite mixed soil specimens after standard compaction testing.
• Varied compaction density and water content to observe changes in permeability.
• Utilized microscopy to examine the microstructure of the compacted specimens.
• Permeability was influenced by bentonite mixing ratios and the dry density and water content during unsaturated compaction.
• Observations indicated that swelling bentonite gel affects the pathways for permeability during testing.
• The process of granulation and flattening during mixing enhances the obstruction and refinement of voids in the soil.
