| Abstract: | The performances of high-performance concrete (HPC) with multi-elements mineral are researched.The performances mainly include the workability,mechanics properties,ability to resist chloride ion penetration and the diffusion coefficient of chloride ion,etc.The shapes of hydras are anlyzed by scan electricity microscope.The action mechanism of that is summarized.The conclusion is that the performance of HPC with multi-elements mineral admixture is superior to that of concrete with a kind of mineral additive.So multi-elements mineral additive should be the better method of mixing high-performance concrete. |

| Keywords: | multi-composite mineral admixture high-performance concrete workability mechanics properties ability to resist chloride ion penetration |
