混凝土由于其取材广泛,价格低廉,成为桥梁结构中最广泛采用的建筑材料。但是由于其抗拉强度低,容易开裂,造成桥梁的耐久性及承载能力降低。因此提高混凝土材料的性能对增大桥梁使用寿命起到一个至关重要的作用。本文通过对多种文献资料的参考分析,总结出了影响桥梁混凝土耐久性的主要因素,并提出一些相关的提高混凝土耐久性的操作方法。
Because of its wide range of drawn concrete, low prices, become the bridge structure of the most widely used building materials. However, due to its low tensile strength, easy to crack, resulting in reduced durability and bearing capacity of the bridge. Therefore, improving the performance of concrete materials to increase the service life of bridges play a crucial role. This paper summarizes the main factors that affect the durability of bridge concrete through the reference analysis of a variety of documents, and puts forward some related methods to improve the durability of concrete.
