Abstract

Concrete structures such as buildings and bridges etc in urban areas may be damaged due to exposure to cloud water with high acidity for a long time. Acid precipitation with a pH level raining between 3.0 and 5.0 will affect concrete. A pH level of rain acid in Korea is between 4.3 and 5.3. However, few studies have been systematically investigated for the effect of rain acid on concrete structures. Therefore, this study is investigated the domestic situation of acid rain and the effect of acid rain on concrete deterioration by existing literatures as a study to analyze the effect of rain acid on concrete structures.
