| 摘 要： | 混凝土常见的因温度引起的裂缝 ,主要存在内外温差 ,如 :外界环境温度变化 ;混凝土刚浇筑时水化热使温度升高等。因热胀冷缩 ,内外变形不一致 ,或受约束 ,产生不同特征裂缝。主要要做好预防 ,施工时做好降温措施。对出现的裂缝及时补强 ,确保结构安全

| Abstract: | The frequent crack of concrete that temperature evocative, because of temperature difference being interior and outer of it. As:The changing of surroundings temperature; Heat of hydration makes temperature increment, and so on. The transmutation in and out of concrete because of physical change, or in harness, it turns out different specificity crack. So we should make prevention and damp down measures when laying out, and strengthen in time when crack appears, which can ensure structure safe. |
