WebApr 1, 2024 · First, the thermal expansion behavior from 30 °C to 105 °C was observed from the dilatometer test with varying dry densities of the compacted bentonite. The change in the lengths of the compacted bentonite buffer materials was measured at a heating rate of 0.5 °C/min, which is the minimum heating rate of the dilatometer.
