| This study examines the effects of heat treatment under laboratory conditions for mixtures of two types of clay (kaolinite and montmorillonite). Clay samples were burned with different temperatures ranging from $100^{circ}C;to;500^{circ}C$. The Atterberg limits such as liquid and plastic limits were influenced with heat treatment. According to the experimental results, the liquid limits slightly decreased between $100^{circ}C;to;300^{circ}C$, whereas rapid decreases were observed after $300^{circ}C$. The plastic limits did not show noticeable differences in the interval $100^{circ}C;to;400^{circ}C$. But the clay samples showed non plastic behavior at $500^{circ}C$. The amount of NaCl was getting decreased with temperature. It also revealed that the pH values were also influenced with heat treatment, and the cation exchange capacity (C.E.C) values decreased with temperature. |
