Description

A study has been completed on the degradation and failure mechanisms in simulated decontamination waste ion-exchange resins solidified in Portland cement. The mixed-bed resins were loaded with LOMI (low oxidation-state metal-ion) reagent and various cationic species to ascertain how they influenced the strength, swelling, set time, and water-immersion integrity of the resultant waste forms. It was found that the properties of the waste forms were very dependent on the composition, as expected, and that different mechanisms for degradation and failure were present for different compositional ranges. 16 refs
