Özet

The aim of this study is to determine the densification of red firing Menemen clay fired at various temperatures. For this purpose, the clay sample was first characterized by chemical analysis, X-ray diffraction (XRD) and plasticity measurements. The mineralogical composition of the clay was dominated by illite/mica, kaolinite, smectite, quartz plagioclase and hematite. The data obtained from plasticity tests indicated that Menemen clay was very high plastic clay. To evaluate firing behaviors, pressed clay samples were fired separately at temperatures between 850 and 1100 degrees C. Fired specimens were evaluated by water absorption, linear shrinkage, bulk density, bending strength, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that there became a significant densification at temperatures especially above 1000 degrees C.
