Abstract:
The advances in cement chemistry and the new cement products, the application of admixtures, additives and fibers can contribute to the formulation study of radioactive wastes cementation. The application status of cement matrices for immobilization of radioactive wastes, including Portland cement, alkali-activated slag cement, calcium sulfoaluminate cement etc. was reviewed. The admixtures, additives and fibers used for improving cemented wastes performance, including wastes loading, compressive strength and long-term durability of cemented wastes were introduced. The objective of this review is to provide some new thoughts for the research and development of radioactive wastes cementation.
