| Abstract: | The test is making water-tight concrete using the technology of adding fly ash and expansion-producing admixture. In this test, we had analyzed properties of fly ash, compared influence of different quantities of fly ash on impermeability of concrete. The results of the test made known that impermeability of concrete from common sil- icate cement is improved after mixed fly ash and expansion-producing admixture. And using this kind of method to produce impermeability concrete has some advantages such as easy operation, convenient construction, low cost, as well as environment friend, and etc.. |
