土木工程中使用的混凝土一般是指以水泥为主要胶凝材料,通过掺加砂、石等增强材料或功能材料,形成的具有一定强度或功能性的水泥基复合材料。作为一种应用广泛的结构材料,混凝土具有可浇筑、经济、耐久、耐火、现场制作等优点,同时也有抗拉强度低、延性低、体积不稳定等缺点。本文主要系统的分析了建筑施工中裂缝产生的原因,以及解决出现裂缝的手段,并介绍了一些修复裂缝的方法。
Concrete used in civil engineering generally refers to the cement-based composite material with cement as the main cementitious material, which is formed by adding reinforcing materials or functional materials such as sand and stone to form certain strength or functionality. As a widely used structural material, concrete has the advantages of being pillable, economical, durable, fire-resistant and on-site fabrication. Meanwhile, it also has the disadvantages of low tensile strength, low ductility and unstable volume. This paper mainly analyzes the causes of cracks in construction and the means to solve the cracks, and introduces some methods to repair the cracks.
