Plant-based concretes Characterization of the vegetable particle / binder interface

Low adhesion of the cementitious matrix on the vegetal particles, as well as poor hydration of the cement are the main causes of these poor mechanical performances, which limits a large-scale production of plant-based composites. The research project focuses on the experiment evaluation of the Interaction Transition Zone (ITZ) between the cement and vegetal for different couple cement/ vegetal particles by visual observations (image analysis, microscopy), microstructural characterization (X-Ray Diffraction, Fourier Transform Infrared Spectroscopy…) and specifically mechanical characterization by micro and nano-indentation.
