| Abstract: | 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. |
