裂缝是混凝土结构中普遍存在的一种现象,它的出现不仅会降低建筑物的抗渗能力,影响建筑物的使用功能,而且会引起钢筋的锈蚀,混凝土的碳化,降低材料的耐久性,影响建筑物的承载能力,笔者主要阐述泵送混凝土温度裂缝产生的原因、温度裂缝的特征及如何防治泵送商品混凝土温度裂缝。同时,对裂缝产生后如何修补提出几点常规施工的参考建议,以供同行参考。
Crack is a common phenomenon in concrete structure. Its appearance not only reduces the impermeability of buildings, affects the function of buildings, but also causes the corrosion of steel bars, the carbonization of concrete, the decrease of the durability of materials and the influence The carrying capacity of buildings, the author mainly describes the reasons for the temperature cracking of concrete pumped, the characteristics of temperature cracks and how to prevent and control the temperature cracking of concrete pumped. At the same time, some suggestions on how to repair the cracks after the conventional construction recommendations for peer reference.
