The purpose of this study is to show the potential of K-based alkali activated materials in the solidification of secondary waste generated in the process of treating contaminated water at Fukushima Daiichi NPP. Therefore, I grasp the physical strength that is important when storing solidified waste, and the amount of hydrogen generation that is important for long-term stability evaluation of solidified waste. I conducted a compressive strength test and a γ-ray irradiation test on a solidified K-based alkali-activated materials without containing simulated waste. In addition, the obtained physical property data was compared with other solidified materials.
