European Joint Programme on Radioactive Waste Management - MAGIC

The MAGIC WP will assess the impact of several simultaneous chemical processes (hydrolysis, multi-ionic attack (i.e. sulfate and magnesium), carbonation) on the mechanical properties of cementitious materials and their evolution. The WP proposes different processes to assess the long-term performance of cement based materials, including a hydraulic transient (re-saturation period with waters from different geological media). It will leverage and build on the advances on past and current European projects (mainly CEBAMA, PREDIS, ACED, DONUT WPs) and explicitly exclude the repetition of activities conducted in these previous or ongoing projects. The final goal is to obtain an improved understanding of chemo-mechanical ageing of cementitious materials exposed to various representative chemical disturbances coming from the disposal environment.
