混凝土中的裂缝可以使混凝土的品质变坏,使构件的承载能力降低,使钢筋的锈蚀加剧,甚至可以导致结构或构件的破坏,因而一直是人们十分重视并致力于解决的问题。混凝土开裂的原因很多,而且同一种原因可能导致形状不同的裂缝,而类似形状的裂缝也可能是由于不同的原因引起的。同时,许多原因的相互作用也不一样,有的是互相加剧,有的则可能是互相抵消。本文主要叙述混凝土中早期裂纹形成的原因,混凝土开裂的原因及预防措施等问题。
The cracks in the concrete can deteriorate the quality of the concrete, reduce the bearing capacity of the components, intensify the corrosion of the steel, and can even lead to the destruction of the structure or the components. This has always been a problem that people attach great importance to and solve. There are many reasons for the cracking of concrete, and the same cause may lead to cracks of different shapes, and similarly shaped cracks may be due to different reasons. At the same time, the interaction of many reasons is not the same, some are exacerbating each other, and others may offset each other. This article mainly describes the causes of early crack formation in concrete, the causes of concrete cracking, and preventive measures.
