(57) [Abstract] [PROBLEMS] To provide a solidifying material suitable for solidifying radioactive waste. SOLUTION: A solidifying material for radioactive waste containing a latent hydraulic substance, an ultrafine powdery substance and a dispersant, and the solidifying material, a curing stimulant, a radioactive waste and optionally water are kneaded and cured for curing. A method for solidifying radioactive waste, which is characterized by the following. [Effect] The solidifying material of the present invention has excellent performance such as high processing capacity, excellent water resistance, and high compressive strength, and can be used not only for temporary storage of radioactive waste but also for permanent storage. |
