红谷隧道沉管后浇带混凝土制备

Preparation of Post-Pouring Joint Concrete for Immersed Tube of Red Valley

针对沉管结构服役条件的特殊性,对沉管后浇带混凝土的工作性能、力学性能、抗渗性能、耐久性能还有抗裂性能进行系统研究,配制适用于红谷隧道沉管后浇带施工的高性能混凝土,实现沉管高性能混凝土的性能均衡发展。

In view of the specialty of immersed tube structure service condition, systematical?research on workability,mechanical property, and anti-cracking ability of post-pouring joint concrete were carried out. High performance concrete was finally prepared which is suitable for immersed tube tunnel construction.
