In the solidification treatment of radioactive waste, high-concentration sodium salts such as carbonates, chlorides and borates are concerned as solidification inhibitors. Therefore, the impact assessment on waste loading ratio and characteristics was investigated in order to confirm the applicability of SIAL^®, which is a geopolymer as a solidification material to the mentioned above sodium salts, compressive strength and fluidity is reported in this presentation.
