Nuclear waste, including the production of watersoluble radioactive metal atoms, is inevitable from the production of nuclear energy, and presents a great threat to human health and to the environment [1]. Immobilization of radionuclides is usually accomplished, first, by binding the nuclear waste in suitable solid waste forms. Subsequently, these waste forms are stored at a repository site having multiple physical and chemical barriers. During the long period of containment, any contaminant release must be limited to permissible rates. This can be ensured by stabilizing radionuclides in suitable binder phases, and restricting groundwater flow which may transport soluble radioactive species outside of the containment zone. Although cementitious materials have been actively used as binder and diffusion barriers because
