Özet

This study examines the effects of heat treatment under laboratory conditions for two types of clay collected from eastern Turkey. Clay samples were burned at different temperatures ranging from 100 to 1000 degreesC. Various clay properties such as liquid limit, plastic limit, optimum water content, maximum dry density and specific gravity were studied. According to the experimental results, the optimum water content rapidly decreased between 100 and 400 degreesC, whereas a few changes were observed between 400 and 1000 degreesC. The maximum dry density increased between 100 and 400 degreesC but this increase was moderate between 400 and 1000 degreesC. The liquid limit rapidly decreased with the temperature ranging from 100 to 300 degreesC, while there was no noticeable difference in the interval of 300 and 1000 degreesC. The plastic limit decreased rapidly between 100 and 400 degreesC. For temperatures higher than 400 degreesC, the soil samples showed non-plastic behavior. The specific gravity rapidly decreased between 100 and 600 degreesC, while it decreased gradually in the interval of 600 and 1000 degreesC. (C) 2003 Elsevier B.V. All rights reserved.
