The clays of this location constitute an interesting area for researchers due to their geology, thickness, and very high overconsolidation values. In the area, clay deposits are unusually thick, varying from 10 m to 60 in in thickness. For this study, geotechnical investigations were carried out with laboratory tests on disturbed and undisturbed samples from seven sites. Geotechnical study indicates that the clays have natural water content range of 6% to 21%, liquid limit range of 27% to 47%, plastic limit range of 13% to 23%, and plasticity index range of 12% to 30%. Doganhisar clays have a medium to high plasticity. Shrinkage limit and specific gravity of clays vary between 10-19% and 2.6-2.8, respectively. The internal friction angle and cohesion vary between 9 degrees-29 degrees and 103-259 kN/m(2), respectively. The consolidation tests show that the swelling pressures and the swelling percents are between 4-10 kN/m(2) and 0.84%, respectively. The composition and geotechnical properties of Doganhisar clays indicate that they are potentially suitable for ceramic and refractory production.eninfo:eu-repo/semantics/closedAccessDoganhisar claysgeotechnical propertiesCentral AnatoliaConference Object107113N/AWOS:000275795400015N/A
