摘要
混凝土收缩裂缝是导致结构服役性能劣化的主因,添加减缩剂成为改善长期耐久性的关键技术措施。基于470篇期刊文献的社会网络分析表明:东南大学为核心研究团队,其研究进程可划分为三个阶段,主要聚焦于减缩机理、开裂机制及混凝土性能优化。基于现有研究分析,完善标准测试方法、明确与其他组分的协同作用机理、深入探究对混凝土性能的影响以及加强在(超)高性能混凝土中的作用研究,或将成为混凝土减缩剂未来的研究方向。
Shrinkage cracks in concrete are the main cause of the deterioration of structural service performance,and the addition of shrinkage-reducing agents has become a key technical measure to improve long-term durability.A social network analysis based on 470 journal articles shows that Southeast University is the core research team in this field.Its research process can be divided into three stages,focusing on shrinkage reduction mechanisms,cracking mechanisms,and optimization of concrete performance.Based on the analysis of existing research,improving standard testing methods,clarifying the synergistic mechanism with other components,in-depth exploration of the impact on concrete performance,and strengthening research on the role in(ultra-)high-performance concrete may become the future research directions of concrete shrinkage-reducing agents.
