| 摘 要： | 通过分析温度对混凝土的损伤机理,尤其是混凝土冻害机理,发展了抗冻临界强度理论和早期结构形成学说,从微观角度定性地描述了负温混凝土防止早期冻害所要形成的结构为抗冻临界界面结构。

| Abstract: | Based on the analysis of the damage mechanism esp.the frost-damage mechanism ,this paper expounds the anti-freezing critical strength theory and structure formation doctrine at early age.It is described qualitatively that anti-freezing critical interface structure is very essential to avoid early frost-damage of nega - tive temperature concrete from the micro-view. |
