Mass transport behaviour of caesium and strontium in geopolymer cements

Key Points

• This research aims to evaluate the transport behavior of caesium and strontium in geopolymer cements for waste immobilization.
• Conducted experiments on geopolymer cements with caesium and strontium
• Measured leach rates of the radioactive fission products
• Assessed durability under different conditions
• Geopolymers showed significantly lower leach rates compared to Portland cement
• Caesium and strontium were effectively immobilized in the geopolymer matrix
• Enhanced durability was observed in the tested geopolymer samples
