Effectiveness of different percentage of bentonite in soil liner on interface shear strength with geosynthetic / Farah Hafifee Ahmad

Interface shear performance of various percentages of bentonite and fine soil were evaluated for landfill stability by conducting Direct Shear Test. The focus of this study is placed on interface shear strength of fine soil and soil with different percentage of bentonite. Bentonite is currently plac...
