Geopolymers have gained attention for their potential in immobilizing radioactive waste. Recent studies indicate that they offer a promising alternative to traditional cement binders. Geopolymers, also known as alkali-activated aluminosilicate cements, help stabilize waste, reducing radionuclide migration. The IAEA is launching a Coordinated Research Project (CRP) to better understand their performance and facilitate deployment. The CRP aims to establish common protocols for assessing waste form performance using geopolymers, promoting consistency among researchers and ensuring compliance with rigorous standards. Ultimately, this contributes to sustainable, efficient solutions for managing radioactive waste
