(TU Delft Geo-engineering) Dijkstra, J. (Chalmers University of Technology) Musso, Guido (Politecnico di Torino) Hattab, Mahdia (Lorraine University) Viggiani, Gioacchino (Université Grenoble Alpes) Contributor Viana da Fonseca, António (editor) Ferreira, Cristiana (editor) Date 2023 Abstract The importance of physico-chemical processes at the particle scale for the engineering scale behaviour of fine-grained geomaterials is undisputed. Yet, despite great advances in the discipline, experimental evidence that fully resolves the clay micromechanics i.e. linking the evolving microstructure and interparticle actions under loading, is lacking. This paper will discuss the challenges ahead in quantifying the evolving kinematics and interparticle interactions of finegrained geomaterials. As such, the current limitations, and the potential opportunities of experimental methodologies for manipulating, monitoring and (post-mortem) analysing fine-grained materials at the particle scale will be discussed. In addition to the need of integrating multiple experimental techniques that span several length scales and modalities, the critical role of advanced data reduction and analysis is highlighted, as required for a measurement as opposed to qualitative observation. Throughout the paper, the link between experimental clay micromechanics and modelling will be discussed.
