Cementitious Systems

Prediction of pathways of radionuclides, heavy metals and other harmful components isolated in cementitious matrices is considered critical in geochemical studies related to hazardous waste disposal [1-3]. Hence, rigorous multi-phase multi-aggregate thermodynamic models with appropriate kinetic and metastability constraints can be very helpful in solving this difficult problem. In a companion contribution [4], we demonstrate that usage of the Gibbs energy minimization (GEM) algorithms permits direct calculation of solid solution – aqueous solution (SSAS) equilibria which adequately describe the solubility data. The suggested "core" thermodynamic dataset can be extended and tuned on the basis of solubility, mineralogical and petrographical studies of fresh, aged and doped cements.
