Abstract
Compacted bentonite which is one component of structure framework of barrier system. The hydro-thermal-mechanical properties of compacted bentonite have been investigated in the past decades in the area such as geoenvironmental engineering (Olivella et al. Olivella et al. 1996). This study conducted creep test for bentonite using a modified relative humidity circulation system. Various vertical stresses were applied on basis of unconfined compressive strength that only relative humidity of 98% as hydration effort influenced to creep behaviour in deformation. Thus, either expansion or shrinkage in vertical direction was measured, and all specimens approached to be completely destruction due to apply the combined effort of mechanical effect and hydration effect.
