摘要:

磷酸基地质聚合物凭借优异的机械性能、耐高温性能和耐腐蚀性,在放射性废物固化领域展现出良好应用潜力。然而,磷酸基地质聚合物的固化机理复杂,且相关研究起步较晚,存在技术研究不够系统、固化机理认知尚不深入等问题。本文系统梳理了磷酸基地质聚合物对不同类型离子及放射性废物的固化研究成果,通过与普通硅酸盐水泥、碱激发地质聚合物的固化机理进行对比,综合评估了磷酸基地质聚合物的固化效果。同时,结合当前研究进展和发展趋势,剖析了磷酸基地质聚合物在放射性废物固化领域应用存在的瓶颈及未来研究方向,为磷酸基地质聚合物固化技术的后续研究与推广提供了方向。

Abstract:

Phosphoric acid-based geopolymers exhibit great application potential for radioactive waste solidification due to their excellent mechanical properties, high resistance for high temperature, and corrosion resistance. However, the immobilization mechanism of phosphoric acid-based geopolymers is complex, and related research starts relatively late, resulting in insufficiently systematic technical research and a lack of in-depth understanding of the immobilization mechanism. This paper analyzes the research progress in the field of phosphoric acid-based geopolymers for immobilizing different types of ions and wastes, and evaluates their immobilization performance by comparing the immobilization mechanisms with those of ordinary Portland cement and alkali-activated geopolymers. In addition, based on the current research progress and trends, this paper discusses the existing problems and future research directions in the application of phosphoric acid-based geopolymers for radioactive waste immobilization, providing insights for the further research and development of phosphoric acid-based geopolymer solidification technology.

Key words: phosphoric acid-based geopolymer, radioactive waste, metakaolin, waste solidification, immobilization mechanism
