Review on Frost Resistance Durability of Self-Compacting Concrete in Freeze-Thaw Environment
摘要: 本文总结了国内外冻融环境下混凝土结构耐久性研究现状及发展趋势，基于对国内外文献的研读与分析，首先对冻融环境下冻融试验方法和标准、混凝土的破坏机理进行了归纳与梳理，深入探讨了孔隙结构、含气量、界面区的冻胀–损伤耦合机制并综述了掺合料、外加剂和骨料种类对自密实混凝土抗冻性能的影响规律和改性机理，随后对该领域未来研究方向进行了展望。
Abstract: This paper summarizes the research status and development trend of durability of concrete structures in freeze-thaw environment at home and abroad. Based on the study and analysis of domestic and foreign literatures, firstly, the freeze-thaw test methods and standards and the failure mechanism of concrete in freeze-thaw environment are summarized and sorted out, and the frost heave-damage coupling mechanism of pore structure, air content and interface zone is discussed in depth. The influence laws and modification mechanisms of admixtures, additives and aggregate types on the frost resistance of self-compacting concrete are reviewed. Then, the future research directions in this field are prospected.
