Strength and Dispersion Studies in Compacted Liner Soil

Abishek Kumar A. A., Meera Manuel

Abstract: In the present day scenario of rapid urbanization and industrialization, large quantities of wastes in different physical forms are generated. Despite all efforts to minimize waste and to neutralize it, the requirement for storage or disposal still exists for which landfills form one of the solutions. According to regulations laid down by Environmental Protection Agency, the soil liners shall ensure that the hydraulic conductivity is equal to or less than 10-9 m/sec, which obviously is the prime criterion in the selection of liner material. Locally available sundried marine soil and its combination with flyash and polypropylene fibres is included in the study. The influence of the flyash and fibres on the permeability and strength characteristics of the above liner materials is studied. Also the dispersion characteristics of the soil treated with flyash and fibre is analysed and a best proportion for flyash and fibres is selected satisfying the liner requirements and a suitable liner is proposed.

Keywords: landfills, flyash, polypropylene fibre, permeability, dispersion
