Abstract
Using low permeability soils in landfill liners is a guaranteed leachate control and prevents leakage which causes environmental pollution. In this matter, the application of new technologies such as nano provides more capable filters that are used for reducing leachate pollutants and modifying the geotechnical properties of liners. The presented study attempted to conduct experimental research on nanoclay–nanofiber composite usage to control landfill liner permeability and observe its impact on the geotechnical characteristics of liners which provide a strong barrel for leachate leakage prevention and increase the liner durability for crack generations. In this regard, a total of 120 different geotechnical experiments were performed on mixed improved fine-grained soil samples which were categorized into four groups including nanoclay additives, nanofiber additives, nanocomposite additives, and control samples (without additives). According to the experimental results, permeability decreased, and geotechnical properties (e.g., Atterberg limits, unconfined compressive strength, cohesion, and friction) were increased with increasing nanocomposite content in the soil.
