混凝土结构产生裂缝的原因和控制

Reason and control of crack of concrete structure

分析了混凝土结构产生裂缝的原因,指出了混凝土产生裂缝的主要原因是受空气的温度和湿度的影响。探讨了控制混凝土产生裂缝的具体措施,指出控制混凝土表面温度的高低,能控制温度应力的产生和积累,减少混凝土表面产生的裂缝。

This paper introduced the reasons for crack in concrete structure, gave the reasons and external factors and internal factors for crack and that the main reason was that concrete was affected by temperature and humidity in air, held that control of surface temperature of concrete could control the producing and cumulating of temperature force to decrease the number of cracks on the surface of concrete.
