耐久性混凝土在铁路建设中的应用

The Application of the Durable Concrete in Railway Construction

随着客运专线及高速铁路的发展,对混凝土工程的使用寿命要求也越来越高,解决混凝土的耐久性问题成为我国近期混凝土技术的主要发展方向。结合公司在建铁路的实际情况,分析了影响混凝土耐久性的主要因素,探讨了混凝土耐久性的设计,研究了耐久性混凝土的性能,提出了现场施工质量的保证措施。

Along with the development of passenger special line and high-speed railway, the requirement for the service life of the concrete engineering is higher and higher, solving the durability of the concrete has become the main development direction of the concrete technology in the recent period in China. Connecting with the actual situation of the railway under construction, this paper analyzes the main factors influencing the durability of the concrete, probes into the design of the durable concrete, studies the performance of the durable concrete, and puts forward some measures for guaranteeing the quality of the field construction.
