For long-term safety storage and disposal of iron slurry embedded into alkali-activated material (AAM), alteration of iron slurry and its interaction with AAM is crucial. In this context, the interfaces between iron slurry and AAM before and after the leaching test were investigated by electron microscopy analysis. No interaction of iron slurry within the AAM matrix was observed in nm space.
