First, the two materials are characterized in-depth. Special attention was paid to sample preparation in order to generate high-quality samples. The evaluation of the test data reveals an increase in friction angle for both materials when using a 1M KCl solution as compared to demineralized water. Kaolinite shows a lower friction angle for the same pore fluid than illite. Future work will further investigate different salt concentrations and different salt types.enClayIlliteKaolinitePore fluidShear strengthTriaxial testTechnology::624: Civil Engineering, Environmental Engineering::624.1: Structural Engineering::624.15: Geotechnical EngineeringConference Paper10.1007/978-981-99-9722-0_160Conference Paper
