重庆轻轨现浇倒T型梁高强、高性能混凝土应用与耐久性研究

Application and Durability Research of HSC and HPC used in Casting-in-Place Inverted T-Beam in Light Rail Project of Chongqing

重庆轻轨大跨倒T型轨道梁要求高精度现浇生产,混凝土设计强度C60,要求百年耐久,在该工程中使用较低的水胶比,选用优质材料及矿物掺合料,配制优质的高性能混凝土,满足重要工程的高耐久性及优良施工性能的要求。

In light rail project of Chongqing, the long-span inverted T-rail beam requests the concrete be produced with high accuracy. The used concrete is HSC and HPC with strength level of C60 and 100-year durability. In this project, high quality materials and mineral admixtures were selected to produce HPc with required high durability and perfect workability.
