On the Sustainable Utilization of Geopolymers for Safe Management of Radioactive Waste: A Review

The application of geopolymers for the safe management radioactive waste has not been implemented on a large scale, where they are tirelessly examined with purpose facilitating practicality and feasibility actual towards sustainable performance these materials. This review therefore compiles findings utilization as sorbents removal radio-contaminants from aqueous streams immobilization matrices containment different wastes. investigated geopolymer base materials encompass wide range reactive aluminosilicate precursor sources that include natural materials, industrial wastes, chemicals. work introduces to reader scientific interest in field studies, their sustainability analysis, nuclear industry, particular treatment immobilization. classification, radiation stability, structural characterizations were summarized special reference characterization structure alteration due inclusion functional or effect metakaolin-based fly ash-based other blend radio-contaminant solutions problematic reviewed analyzed identify gaps Finally, perspectives presented, identified included need investigate new areas application, e.g., pretreatment membrane separation. reusability regeneration sorbents/exchangers be addressed reduce material footprints this application. Moreover, there is develop durability tests standards based record geopolymers.
