Recent advances in tailings waste as geopolymers for construction: Current challenges and prospects

This review article explores the utilization of mine tailings waste in the production of geopolymer construction materials, focusing on their potential to contribute to environmentally sustainable building practices. Geopolymers, derived from aluminosilicate-rich mine tailings, offer a promising alternative to traditional building materials by mitigating environmental pollution and lowering production costs. The paper examines how optimizing synthesis conditions enhances the mechanical properties and durability of geopolymers. Furthermore, it highlights the environmental benefits, particularly the stabilization of heavy metal ions within the geopolymer matrix, which is crucial for preventing environmental contamination. The review synthesizes recent advancements in the field, providing comprehensive insights into the chemical and mechanical characteristics of tailings-based geopolymers. It also discusses the challenges and prospects of integrating mine tailings into geopolymer production, aiming to promote sustainable construction practices and effective mining waste management.
