混凝土现浇板裂缝的原因及防治

混凝土在现代工程建设中的应用非常广泛,混凝土以其优良的耐久性、耐火性、整体性、可模性和易于就地取材的特点为我们提供了一种优异的工程材料;然而,混凝土同样也存在着一些难以克服的缺陷,抗裂性能差即是其主要缺陷之一,它造成的混凝土裂缝几乎无所不在,这一现象在楼面、桥面、路面等现浇板式构件中尤为常见,本文仅就混凝土现浇板裂缝的原因及防治进行分析和阐述。

concrete is widely used in modern project construction.Because of its durability,fire resistance,integrity,mouldability,and easiness to be locally obtained,concrete provides us with quality project materials.However,concrete has some shortcomings that are difficult to overcome,one of which being its poor crack- resistance.Due to poor crack-resistance,concrete plate cracks are everywhere.They are especially found on the floors of buildings,the floors of bridges,the surfaces of roads and other components of cast plates.The article mainly to analyses and discusses the causes and prevention of cracks of newly-made concrete plates.
