Sorption of radionuclides onto C-S-H and C-A-S-H at various degradation stages KU Leuven
Cementitious materials are ubiquitous in the current designs of both surface and geological disposals of radioactive waste. Calcium-silicate-hydrate (C-S-H) and calcium-aluminate-silicate-hydrate (C-A-S-H) are the most important hydration products of cement and also the main sorbing phases with respect to radionuclides. On the time scales of a nuclear waste repository, the cement phases will degrade and their physico-chemical properties will ...
