Zusammenfassung:This review paper provides a comprehensive analysis of cement-based solidification and immobilisation of nuclear waste. It covers various aspects including mechanisms, formulations, testing and regulatory considerations. The paper begins by emphasizing the importance of nuclear waste management and the associated challenges. It explores the mechanisms and principles in cement-based solidification, with a particular focus on the interaction between cement and nuclear waste components. Different formulation considerations are discussed, encompassing factors such as cement types, the role of additives and modifiers. The review paper also examines testing and characterisation methods used to assess the physical, chemical and mechanical properties of solidified waste forms. Then the paper addresses the regulatory considerations and compliance requirements for cement-based solidification. The paper concludes by critically elaborating on the current challenges, emerging trends and future research needs in the field. Overall, this review paper offers a comprehensive overview of cement-based solidification, providing valuable insights for researchers, practitioners and regulatory bodies involved in nuclear waste management. •Thoroughly explores cement-based nuclear waste solidification, covering mechanisms, formulations, testing, and regulations.•Highlights the critical role of nuclear waste management, acknowledging associated challenges.•Delves into intricate mechanisms governing cement-solidified waste, offering a detailed understanding.•Examines additives, modifiers, and cement types, providing nuanced insights into solidification processes.
