| 摘 要： | The effect of w/c ratio,incorporation of silica fume and maximum aggregate sizes on permeabilityof concrete were studied.The test results both from chloride permeability and water absorptionshowed that the permeability of concrete increased as the w/c increases whilst a limitedamount of replacement of cement with silica fume the permeability decreased significantly.Themaximum aggregate size in the range of 8 to 25 mm seems also affect permeability but with a muchless significant level. A linear relationship between chloride permeability and capillary absorptionwas found.

| Abstract: | The effect of w/c ratio,incorporation of silica fume and maximum aggregate sizes on permeability of concrete were studied. The test results both from chloride permeability and water absorption showed that the permeability of concrete increased as the w/c increases whilst a limited amount of replacement of cement with silica fume the permeability decreased significantly. The maximum aggregate size in the range of 8 to 25 mm seems also affect permeability but with a much less significant level. A linear relationship between chloride permeability and capillary absorption was found. |
