混凝土的裂缝是施工中具有较普遍性的质量问题,混凝土结构、构件出现裂缝,不但影响建筑外观,而且有可能影响构件刚度和结构整体性。当裂缝宽度超出一定限度,有时会造成钢筋锈蚀,影响结构构件的耐久性,因此,对裂缝的出现,应给予应有的重视。通过多年的现场施工,通过查阅有关混凝土内部应力方面的专著,对混凝土裂缝的控制措施等进行阐述。 Concrete cracks are the construction of the more common quality problems, cracks in concrete structures, components, not only affect the appearance of the building, but also may affect the structural rigidity and structural integrity. When the crack width exceeds a certain limit, sometimes cause corrosion of steel bars, affecting the durability of structural components, therefore, the emergence of cracks should be given due attention. Through many years of on-site construction, through the access to the monograph on the internal stress of concrete, concrete crack control measures are described.
