摘要
介绍了所研制的一套测试混凝土气体渗透系数的实验装置 ,并从理论上推导了利用该方法测试气体渗透系数的计算公式 .与Cembureau法进行的对比试验结果证明 ,在同条件下两者所测数据的线性相关性较高 .实验证实 ,本方法具有操作简便、密封性能好、测试数据可靠的特点 ,以此方法来评价混凝土的气体渗透性能是合理可信的 .
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.
