Abstract Summary
Storage of nuclear wastes in deep geological disposals is an important concept in terms of energy geotechnics. The long-term heat released by nuclear waste causes changes in the structure of the buffer material bentonite clay. Hence, it is critical to determine the short and long term engineering parameters of bentonite clay under high temperature. In this study, short and long term compressibility behavior of calcium bentonite clay and glass fiber-bentonite mixture under high tem-perature were investigated.
