Investigation of the Leachate Effect on Permeability and Geotechnical Characteristics of Fine-Grained Soil Modified Using Nanoclay–Nanofiber Composites

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 pollutants modifying geotechnical properties liners. The presented study attempted to conduct experimental research on nanoclay–nanofiber composite usage liner observe its impact characteristics provide strong barrel prevention increase durability crack generations. regard, total 120 different experiments were performed mixed improved fine-grained soil samples categorized into four groups including nanoclay additives, nanofiber nanocomposite (without additives). According results, decreased, (e.g., Atterberg limits, unconfined compressive strength, cohesion, friction) increased with increasing content soil.
