混凝土有很多优点,它承受荷载的能力很大,而且可以根据人们的意愿塑造成任意形状。因此,它是当代最重要的建筑材料之一。但是混凝土也有美中不足之处,它很容易开裂,这不仅影响美观,容易引起工程各方纠纷,而且由于裂缝的存在和发展通常会使内部钢筋等材料产生腐蚀,降低钢筋混凝土材料的承载能力、耐久性及抗渗能力,影响结构的使用寿命,严重的将威胁到人民的生命、财产安全,因此,混凝土裂缝也越来越受到行内人士的高度重视。
Concrete has many advantages, it has a great ability to withstand loads and can be shaped into any shape according to the wishes of the people. Therefore, it is one of the most important building materials of our time. However, concrete also has its drawbacks. It is easy to crack, which not only affects the appearance, but also easily leads to disputes among all parties in the project. In addition, due to the existence and development of cracks, corrosion of internal steel bars and other materials usually occurs, reducing the carrying capacity of reinforced concrete materials and durability Sexual and impermeability, affect the service life of the structure, will seriously threaten the life and property safety of the people. Therefore, the concrete crack is also paid more and more attention by the insiders.
