Effect of glass-fiber on mechanical performance and microstructure of bentonite-fly Ash and bentonite-sand mixes for landfill liner application

Key Points

• Mechanical performance significantly improves with the addition of glass-fiber in soil mixtures, enhancing durability.
• The study shows that modifications to the microstructure lead to better performance under landfill conditions.
• Observational analysis of bentonite-fly ash and bentonite-sand mixes reveals varied results with glass-fiber incorporation.
• This suggests potential for improved landfill liner systems, yet application in real-world scenarios requires further examination.
