摘要
综合论述了国外对混凝土在超低温下的力学、热工、冻融、收缩等性能的最新研究进展,讨论了在超低温下混凝土中水相变机制与力学增强机理,并进一步指出未来应加强对超低温下混凝土内部孔中水的相变机制及冻融循环破坏机理等方面的研究。
State-of-art research on properties of concrete such as mechanical, thermal, freezing-thawing and shrinkage properties etc. at cryogenic temperature overseas are summarized comprehensively. Phase change mechanism of water and mechanical performance-reinforcement mechanism of concrete at cryogenic temperature is discussed. The research directions in the future are pointed out including phase change mechanism of water in pores and freezingthawing deterioration mechanism of concrete at cryogenic temperature as well.
