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...

Foundations 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 placed for use as buffer and backfill materials in landfill because these materials create an impermeable zone where it reduced the potential of soil contamination from leachate. In this study, direct shear box with dimension of 60 mm x 60 mm was used to determine the interface shear strength of soil with different percentage of bentonite at optimum moisture content. Normal stresses used were between 100 kPa to 300 kPa to represent the depth of 20 m metres of solid waste. Results showed that the most suitable percentage of bentonite was 5% due to the highest interface shear strength of the mixture with non woven geosynthetic. Moreover, even the presence of bentonite in the sample is proved to give higher interface shear strength to the tested soil, additional bentonite tends to decreased it shear strength. 2013 Thesis https://ir.uitm.edu.my/id/eprint/16269/ https://ir.uitm.edu.my/id/eprint/16269/1/TM_FARAH%20HAFIFEE%20AHMAD%20EC%2013_5.pdf text en public mphil masters Universiti Teknologi MARA Faculty of Civil Engineering
