Soils usually have many problems which limit their use in engineering constructions. There are many methods available for solving problems with soils, including the method of heat stabilization. This method has not been considered appropriate for engineering applications in the USA because of the high energy cost associated with it. A better understanding of the effect of heating on the engineering properties of soil would help in making this method economical and appropriate to use. This study investigates the effect of heating on some engineering properties of two clay soils. An experimental study on the effect of heating on swelling, consolidation, and strength properties of a kaolin and a bentonite was done. Specimens of Edgar Plastic Kaolin and Western Bentonite prepared at a void ratio of 1.0 and 1.2 were tested dry, fully saturated and heated to different temperatures up to 600. The test results were analyzed, compared, and explained. It is found that heating kaolinite to a temperature of up to 300 caused the elimination of its free and adsorbed water. Heating to a higher temperature, 400, reduced its swelling and consolidation and further heating to 500 resulted in increasing its strength. On the other hand, heating bentonite to 300 resulted in the elimination of its free and adsorbed water, while heating it to 600 changed it to a nonexpansive state, reduced in consolidation, and increased in shear strength. From the test results, it was found that soft clay soils can be stabilized effectively without heating to a very high temperature. This will help in minimizing heating costs and, thus, make this method economical and appropriate.
