高性能混凝土在特大桥梁建设中的应用

Application of High Performance Concrete in Super Bridge Construction

针对高性能混凝土早期体积稳定性差、容易开裂的缺点,从高性能混凝土的配制方法、耐久性指标的控制要点和检测方法等三个方面进行过程控制,有效提高了高性能混凝土的抗裂性和耐久性,为特大桥梁建设过程中正确使用高性能混凝土积累了经验。

Aiming at the detect of the volume stability,frigility of high performance concrete in the early stages.Process control in the preparation method of high performance concrete,the control is key point of the endurance nature index and detection method.At last the resistance of crack and durability of the high performance concrete effectively and accumulate experience for using the high performance concrete correctly in super bridge construction process are improved.
