| Abstract |
| This paper is a study from mineralogical and physico-chemical points of view about
the possibility of using Arslanlar clay in tile and brick industry. Firstly, chemical
analysis, X-ray diffraction (XRD), differential thermal analysis/thermogravimetry and
plasticity measurements were performed to determine the unfired characterization
of the clay sample. It was observed that illite, smectite, kaolinite, calcite, hematite,
orthoclase and quartz were the main minerals. Plasticity tests revealed that Arslanlar
clay was very high plastic clay. Then the clay test samples were prepared by pressing
and firing separately at temperatures between 850o and 1100oC to evaluate physicochemical
characteristics. Water absorption, linear shrinkage, bulk density, bending
strength tests and colour measurement were performed. Also the fired samples were
analyzed by XRD and scanning electron microscopy. It was observed that the porosity
decreased and the densification increased with increasing temperature, especially
above 1050oC. Evaluations concluded that this clay can be used in production of
structural ceramics and also pottery.
