Abstract
A simple test method is developed for determining the thermal diffusivity of solds and granular materials by measuring the time at which the peak on a temperature-time record occurs. It allows the use of small easily prepared specimens and specimens of irregular shape (for example, stones). The tests can be performed at room temperature as well as at high temperatures, and can be repeated in short time intervals.
