摘要: 为了将建筑废弃物资源利用实现环境美化的问题，提出地质聚合物(Geopolymer)作为一种绿色建筑材料，具有替代硅酸盐水泥的潜力，因其具有固废资源利用和原料广泛等优点，有望实现低碳环保目标。基于此，本文研究了地质聚合物的反应机理和力学性能影响因素；分析了碱激发剂、凝胶材料、水胶比对GPC胶凝分子的影响，总结了固废秸秆灰理化性质、作用机制、性能影响以及对地聚物的研究；掌握了废砖再生骨料物理性质、化学改性以及对地聚物的研究；介绍了地聚物的微观分析和界面强化。旨在为固废基地质聚合物中的发展研究提供理论支持和技术借鉴。
Abstract: In order to solve the problem of environmental beautification by using construction waste resources, Geopolymer is proposed as a green building material, which has the potential to replace Portland cement. Because of its advantages of solid waste resource utilization and wide range of raw materials, it is expected to achieve low-carbon environmental protection goals. Based on this, this paper studies the reaction mechanism of geopolymer and the influencing factors of mechanical properties; the effects of alkali activator, gel material and water-binder ratio on GPC gelling molecules were analyzed. The physical and chemical properties, action mechanism, performance influence of solid waste straw ash and the research on geopolymer were summarized. Mastered the waste brick recycled aggregate physical properties, chemical modification and the study of geopolymer; the microscopic analysis and interface strengthening of geopolymers are introduced. The aim is to provide theoretical support and technical reference for the development of solid waste-based geopolymers.
