Area index of airborne chlorides at the seashore in Korea

우리나라 해안의 비래염분에 대한 지역계수 산정

Concrete structures in the seashore are greatly affected by salt attack primarily due to airborne chlorides like it can be seen through the corrosion of rebar. This study intends to investigate characteristics on the salinity of the airborne chlorides in terms of areas. Salinity measurement devices were installed at 27 areas along with seashore throughout the country. The area index for airborne chlorides were established according to the measurements. In Gochang and Taean area showed higher value of area index over 10. In addition, the Eastern coast showed higher index compared to the Western and Southern coast.
