Özet:

 Bentonite-containing mixtures, which are used as an impermeable engineering barrier in waste disposal facilities and energy geostructures, are exposed to thermal changes over time. It is very important for the performance of energy geo-structures and environment and human health that the soils are maintained for a long time without deterioration of their engineering properties under these thermal changes. In this study, the effects of temperature 20 and 80 C and temperature cycles on the shear strength behavior of compacted sand-bentonite and zeolite-bentonite mixtures were investigated. In addition, tincal, which is a boron mineral and has high temperature resistance, was added to these mixtures and its effect on the shear behavior of these mixtures at high temperatures was investigated. The shear strength of the mixtures generally increased between 5 and 15 with increasing temperature. In addition, the addition of tincal was found to be beneficial in terms of shear strength, especially for sand-bentonite mixtures.

 Atık depolama alanları ve enerji geo-yapılarında geçirimsiz mühendislik bariyeri olarak kullanılan bentonit içerikli karışımlar zamanla termal etkiler altında değişimlere maruz kalabilirler. Zeminlerin, bu termal değişimler altında mühendislik özelliklerinin bozulmadan uzun süre korunması enerji geo-yapısının performansı ve çevre ve insan sağlığı için oldukça önemlidir. Bu çalışma kapsamında, sıcaklığın 25 ve 80 C ve sıcaklık döngülerinin sıkıştırılmış kum-bentonit ve zeolit-bentonit karışımlarının kayma dayanımı davranışı üzerindeki etkisi araştırılmıştır. Ayrıca sıcaklığa karşı direnci yüksek bir bor minerali olan tinkal, karışımlara ilave edilmiş ve bu katkının yüksek sıcaklıklarda karışımların kayma davranışına etkisi incelenmiştir. Karışımların kayma dayanımı genel olarak artan sıcaklıkla 5-15 aralığında artış göstermiştir. Ayrıca tinkal ilavesi özellikle kum-bentonit karışımları için kayma dayanımı açısından faydalı bulunmuştur.
