Abstract
Considering the chemical reaction between concrete which is the raw material of the dike bottoms and hazardous chemicals, some chemicals can have negative effects on the impermeability of concrete dike bottoms. The impermeable standards for the concrete bottom of dikes have been made in the recent study, but the previous study was based on the exposure test to crude oil which is not corrosive and not related to the chemical reaction. It can be concluded that the test of crude oil can't represent all kinds of hazardous chemicals, especially highly corrosive chemicals. Meanwhile, this study has conducted the exposure test to nitric acid that is strongly corrosive and very hazardous. The results have showed that nitric acid has been penetrated at the maximum penetration depth of 2.9 cm for 7 days and the impermeable standards are better than the germany standard. Through this study with severe chemical, the scientific basis on the installation standards of all dike bottoms which are generally used in the industry has been obtained.
