| Abstract: | Combined with the No.2 Changjing River great bridge construction, The effect of the mechanical performance and the long age durability with the different content of fly ash in HPC is researched. The result show that the C50 HPC with 24 percentage grade I fly ash have good workability, mechanical and long durability. Specialy, the concrete have low shrink and creep, those are benificial to the pretressed concrete in the bridge construchion |
