Abstract

Cementitious binders are commonly used to solidify/stabilize hazardous wastes prior to disposal in multi-barrier engineered disposal facilities or landfills. Because they are not in equilibrium with other materials in a landfill, cementitious materials usually degrade with time. Reactive transport models may be used to estimate the possible effects of changing geochemical conditions on the transport properties of the cementitious materials, the leaching of chemotoxic elements from the waste form, and alterations of the sorption properties of surrounding materials due to leaching of cement components
