Construction and Quality Evaluation of Prestressed High-Strength Concrete Hollow Slabs
Combined with the application of high-performance concrete in bridge engineering, the construction technics of pretensioned prestressed high-strength concrete (PPHC) hollow slabs with new section is summarized. The qualities of concrete in C80 strength grade are statistically analyzed based on the precast of 75 PPHC hollow slabs for two bridges. The results show that it is reliable to precast PPHC hollow slabs for bridge construction.
