This paper presents the physico-hydro-mechanical properties of a commercial bentonite
in Indonesia related to the possibility of its use as a barrier in the waste repository. Physical properties include specific gravity, Atterberg limits, grain distribution, and compaction. Methods used to determine physical properties followed ASTM standards procedures. X-ray diffraction (XRD) and Environmental Scanning Electron Microscopy Test (ESEM) were also utilized in order
to investigate the mineral content and microscopic level of the bentonite, respectively. The
hydraulics properties of the bentonite (i.e., permeability and water retention) were obtained from permeability test and chilled-mirror hygrometer test, respectively. The mechanical property of the material includes the shear strength which was determined by using direct shear tests, respectively. The results are compared to other bentonites that have been widely used in the world.
