| Abstract: | Combined with the Wuhekou cable-stayed bridge engineering,two kinds of fly ashes and coarse aggregates were tested to analyze the affections between aggregates and mechanical performances of the HPC.Through optimized different mixing ratio of fly ashes with aggregates,in both items and amounts, C50 HPC mixing proportions satisfing workability and strength of the pylon were achieved.Meanwhile examinations of the mechanic performances and durability were carred out. |

| Keywords: | high performance concrete fly ash optimum mechanical properties durability application |
