Shear Strength Behavior of Perlite Added Sand-Bentonite Mixtures Under Room Temperature and Thermal Cycles
The present study investigates the shear strength behavior of perlite added sand-bentonite mixtures under room temperature and thermal cycling. The increase in the number of energy structures causes interaction of soils with high temperature. Thermally durable soil material is needed around energy geo-structures. In this study, it was aimed to obtain a new buffer material to be used around energy structures by adding 10 and 20% perlite additive to 20% bentonite-80% sand mixtures (20B-80S). The direct shear tests were conducted under temperature cycling (8 hrs heating-16 hrs cooling). As a results of the compaction tests, it was seen that the perlite additive decreased the maximum dry unit weight (γdry-max) and increased the optimum water content (wopt). The test results showed that perlite additive reduced the shear strength of the mixture under thermal cycles but with 20% perlite additive reached higher strength than 10% perlite additive.
