In energy geo-structure and landfill applications, the effect of temperature on the behavior of soils should be considered. Some properties of soils surrounding structures which are nuclear waste disposal facilities, landfills, energy piles, etc. may change with increasing temperature. According to previous studies, properties of soils such as; volumetric deformation, shear strength, permeability are affected by high temperatures and thermal cycles. For that reason, in such geotechnical applications, there is a need for soils that are not negatively affected by high-temperatures, that is, that can maintain or improve their properties at high temperatures. Zeolite-bentonite mixtures may be proposed as an alternative to sand-bentonite mixtures in impervious barriers. Zeolite is preferred because of its high cation exchange capacity, which is not present in sands. In this study, 10% tincal and perlite were added to the mixtures which are bentonite/bentonite-zeolite ratio of 0.20 because of their superior properties at heat insulation. The compaction and direct shear tests were performed at room temperature and 80 °C.
