近年来,随着社会经济的快速发展,基础建设投入迅速增加,各地兴建了大量的混凝土建筑,而混凝土的裂缝是建筑工程中普遍存在的问题。微裂缝不会影响工程的质量,但过宽的裂缝会引起混凝土中钢筋的锈蚀,降低结构的耐久性;损坏结构的外观,影响正常使用;严重的还会影响结构的安全。混凝土构件产生裂缝的因素很多,本文就混凝土裂缝的成因、控制与修补浅谈几点看法。
In recent years, with the rapid social and economic development, the investment in infrastructure has rapidly increased, and a large number of concrete buildings have been built around the country. Concrete cracks are a common problem in construction projects. Micro-cracks will not affect the quality of the project, but too wide cracks will cause corrosion of steel bars in concrete, reducing the durability of the structure; damage the appearance of the structure, affecting the normal use; serious will also affect the safety of the structure. There are many factors that cause cracks in concrete structures. In this paper, the causes, control and repair of concrete cracks are briefly discussed.
