Sawdust, Clay, Landfill Liner


A landfill liner is the component of landfill that serves as a barrier system to minimize contaminant migration from the landfill to ground water table. This report investigates how the application of sawdust influences the geotechnical properties of bentonite in order to determine its suitability for use as landfill-liner. A series of laboratory tests were conducted on unstabilized and stabilized clay in order to determine the effects of various proportions of sawdust (1,2,3,…,6% ) on the stabilisation. Results show that liquid limit, plastic limit and maximum dry unit weight of the soil decreased with increasing sawdust content while the optimum moisture content and hydraulic conductivity increased with increasing sawdust content. The stabilization of the bentonite with ≤ 5% sawdust content was recommended for use as landfill liners, as they meet the liner requirements.
