Résumé

The CEMTEX project in the Tournemire URL studied the temperature effect on the in situ evolution of CEM-I and low-pH cement pastes in contact with argillite after 1, 2 and 5 years, in the context of radioactive waste disposals. Reactive transport modeling was used as a tool to support the most significant experimental results, e.g. occurrence of zeolite and well-crystallized C-S-H at the interface and reduction of cement alteration depth with temperature for CEM-I, but M-S-H precipitation and increase of alteration depth with temperature for low-pH cement.
