Abstract :Thermal changes insert ignore into journalissuearticles values(high temperature and thermal cycles); occur around energy structures, such as energy piles, nuclear waste repositories, etc. Sometimes these temperature changes affect the engineering properties of surrounding soils undesirably. Hence, there is a need for durable soils that can maintain their engineering properties unchanged under high temperature and thermal cycles for a long time. Tincal and pumice are used in the production of temperature-resistant and heat-insulated materials. Therefore, in the present study, 10% and 20% tincal and pumice additives were added to zeolite-bentonite mixtures and shear strength behavior of the mixtures was investigated under room and high temperatures insert ignore into journalissuearticles values(80°C);. According to the results, the maximum shear stress values of zeolite- bentonite mixtures generally increased in the presence of tincal and pumice additives under high temperature. Both additives are effective for improvement, however; the effect of pumice can be more pronounced.
