Aluminosilicate phosphate (ASP) geopolymers are a new kind of green cementitious materials synthesized from aluminosilicate precursors and acidic activators (phosphoric acid or phosphate), which have received extensive attention from researchers because of their excellent and unique characteristics. The current investigation indicates that ASP geopolymers have the characteristics of a low-carbon synthesis process, high mechanical properties (e.g., the highest compressive strength can reach 146 MPa), a strong heat resistance (e.g., withstanding a high temperature of 1500 °C), and excellent dielectric properties. These excellent properties make them have broad application prospects in the fields of new building materials, coating materials, insulating materials, and heavy metal curing. Based on the research findings of approximately 85 relevant literatures on ASP geopolymers in past decades, this paper focuses on the latest research progress of ASP geopolymers from the perspectives of synthesis processes, performances, modifications, and application developments. In addition, this study summarizes the key problems existing in the current research of ASP geopolymers and suggests their possible applications in the future, which will help to provide directions for further research activities of relevant researchers.
磷酸铝硅酸盐（ASP）地质聚合物是一类新型绿色胶凝材料，由铝硅酸盐前驱体和酸性活化剂（磷酸或磷酸盐）合成，因其优异独特的性能而受到研究人员的广泛关注。目前的研究表明，ASP地质聚合物具有低碳合成工艺、高力学性能（如最高抗压强度可达146MPa）、强耐热性（如能承受1500℃高温）以及优异介电性能等特点。这些优异性能使其在新型建筑材料、涂料、绝缘材料和重金属固化等领域具有广阔的应用前景。基于过去几十年约85篇关于ASP地质聚合物的相关文献的研究成果，本文从合成工艺、性能、改性及应用发展等方面重点阐述了ASP地质聚合物的最新研究进展。此外，本研究总结了当前ASP地质聚合物研究中存在的关键问题，并提出了其未来可能的应用方向，这将有助于为相关研究人员的进一步研究活动提供指导。
