State-of-art Review on Properties of Concrete at Cryogenic Temperature Overseas

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 freezing-thawing deterioration mechanism of concrete at cryogenic temperature as well.
