This study investigates the control of cesium (Cs) leachability in cementitious binders, which is critical for the safe immobilization of nuclear waste that poses risks to human health and the environment. The objective is to explore how various additives can enhance the sorption of Cs within cement matrices. The methodology focuses on employing a series of experiments to evaluate the impact of different components such as reactive silica, fly ash, and glass powder on the leaching behavior of radioactive waste forms. Results reveal that incorporating glass powder significantly reduces the leach rate of cesium from cement by one-tenth compared to plain cement, while also enhancing the solidification of borates present in waste streams. The findings indicate that by carefully tailoring the chemical makeup of cement composites, it is feasible to mitigate the leachability of highly mobile radionuclides like Cs and strontium (Sr), thus improving the performance of cementitious materials in nuclear waste applications. This research underscores the importance of optimizing cement formulation for better containment of hazardous materials.
