Abstract

Language:

Portland cement blended with fly ash and attapulgite clay was mixed with high-alkaline solution simulating low-level radioactive waste stream at a one-to-one weight ratio. Mixtures were adiabatically and isothermally cured at various temperatures and analyzed for phase composition, total alkalinity, pore solution chemistry, and transport properties as measured by impedance spectroscopy. The total alkalinity is characterized by variations depending on the curing conditions, indicating the interactions between the cement components and the alkaline solutions. Results show significant changes in the transport properties of the mixtures, suggesting that the incorporation of clay materials can enhance the containment potential of cement-based systems for storing alkaline waste. This study thus provides insights into optimizing blended cements for applications related to environmental restoration and the management of low-level radioactive waste solutions.
