高性能混凝土在桥梁建设中的施工应用

Application of High-performance Concrete in Bridge Construction

为保证桥梁的耐久性,工程施工中多采用高性能混凝土。这种便于浇捣、不离析、力学性能稳定、早期强度高、具有韧性和体积稳定性等性能的耐久混凝土,特别适用于暴露在严酷环境中的桥梁工程。简要分析了高性能混凝土的特性及其在公路桥梁建设中的应用。

High-performance concrete is used for the durability of bridges in construction.The concrete of high-quality material is easy to cast and hard to segregate,mechanically stable,strong in early stages,flexible and stable in volume,and it is especially used in bridge construction in harsh environment.The paper briefly analyzes the characteristics and application of the high-performance concrete in highway bridge construction.
