• This is a report of a preliminary study which was conducted prior to consolidation tests on the same kinds of clay undergoing elevated temperatures. It was considered imperative to examine at the beginning of study whether or not the planned heating affects the fundamental nature of clays. Therefore, the tested clay powders were heated in an oven under at the highest 200℃, followed by cooling and running those conventional tests on Atterberg limits, free swelling, and unconfined compression. Those tests revealed that pre-heated powders behaved in the same manner as unheated powders. Moreover, microscopic investigation did not detect a perceptible change in the appearance of clay after heating. Consequently, it was concluded that the employed range of heating does not influence the soil-mechanic nature of clay particles, and that the thermal effects should occur only through the interaction between clay grains and pore water.
