| Abstract: | Large number of tests have proved that fly ash not only can improve concrete＇s workability, reduce the early hydration temperature rising of concrete, improve the interface structure of concrete, but also can cause cement concrete＇s compression resistance, bending resistance, permeability resistance and salt-freezing resistance to be superior than ordinary cement concrete. |

| Keywords: | ement concrete mix proportion fly ash permeability salt-freezing resistance |
