Abstract: The rockfill dams, usually use in huge hydraulic geotechnical, exposures to water and aggressive solutions such as: seawater, acid mining drainage. In particular, the mechanical properties of rockfill dams is depended on volumetric deformation. However, the volumetric deformation of rockfill dams depends on as well as the contact solutions inducing different chemical reaction. The chemical reaction leads to the modifications of rockfill dams mechanical behaviour such as irreversible settlements. The modifications evolve over the time. To relatively predict the chemical degradation rockfill dams, the geochemical modelling is used to simulate chemical reactions between heterogeneous particles or different mineral of rockfill dams. The model can predict relatively the long-term material performance of rockfill dams exposure to different environment such as acid mining drainage and seawater.
