Assessment of two thermally treated drill mud wastes for landfill containment applications

摘要

The current paper has presented the results of physical and chemical index tests, mineralogical analyses, chemical analyses, and geotechnical hydraulic and strength tests performed on TTDMW-UK and/or TTDMW-NS samples to assess their likely suitability for use in landfill containment systems. Shear strength tests revealed no major stability concerns for moderate slope angles, although there may be some environmental regulatory issues associated with their use. However, several options are offered to overcome these potential obstacles.
