In order to estimate soundness of geopolymers (GP) after long-term exposure to water, we are trying to develop a method to accelerating GP deterioration. This time, we evaluated void structure and Sr sorption partition coefficient (Kd) of GP after hot water exposure. As a result, a correlation was found between void and Kd over a period corresponding to 2872 years. This indicates that it may be possible to estimate Kd by predicting the change in the amount of void in the GP.
