| Abstract: |
| An experimental arrangement for the test of the gas permeability coefficient of concrete was introduced. A calculate formula for coefficient permeability was derived from theory. The test result was compared with the experimental data measured by Cembureau method. The result showed that the linear relationship between the data based on two methods is good. This test method has the advantages of simple on the operation and good of airproofness. It is believable and reasonable to use this method for assessing the gas permeability property of concrete. |
