Abstract
This study is on a suggestion of the evaluation method of O3 deterioration of waterproofing and corrosion prevention materials in concrete facility for advanced water treatment using ozone(O3) sterilization. Generally, drinking water has been sterilized with chlorine. But chlorine is not removed by means of smell and taste and organic pollutants such as ammonia nitrogen. So, in advanced water treatment, ozone (O3)treatment, biological treatment and activated carbon are using for remove of smell and sterilization of drink water. And this advanced water treatment facility(structure) is made with concrete. For the protection of concrete from
chemical attack by chloride, generally so many materials had been used on concrete surface as corrosion protection coatings. But strong oxidation of ozone decrease the durability of rubber or resin materials applied on the surface of concrete, those materials attacked by ozone (O3) are uncleared weather have the corrosive protection effect of not, and also there is not the evaluation or test methods about ozone effect to materials.
So, in this study, some ozone test methods are suggested for evaluation of ozone (O3) influence to corrosive protection materials.
