During this internship, you will implement this protocol in the laboratory, then characterize the crack network obtained by different methods such as SEM-EDS and tomography, or even via leaching experiments. Different parameters will be measured such as the cracking rate, the specific surface area developed, the length of the cracks or their opening. The reproducibility of the method will also be evaluated. Depending on the results and with the aim of being as representative as possible of the network of cracks actually developed in the glass blocks at scale 1 (Repina, 2019), the protocol can be optimized. This subject then opens onto a thesis continuation.
