To secure the anticorrosive performance of structures in the oceanic environment it is necessary to select appropriate finishing materials and thickness of cover. However, airborne chloride deposition varies depending on the collector used, and it is difficult to select appropriate finishing materials. For this reason, an eight-directional collector is proposed in this study through reviewing the differences between existing airborne chloride collectors and the new one. To analyze airborne chloride deposition according to the direction from which it flows and verify the performance of the collector proposed in this study, airborne chlorides were deposited on the collector for one year at five different locations in an oceanic environment. From the experiment, it was verified that in terms of direction, there were differences in airborne chloride deposition of up to more than 1.5 times. Based on these research findings, the anti-corrosive method applied can be different for each side of a building's structure, and this is believed to serve as an effective and systemic chloride resistance design.

The newly developed eight-directional collector was installed at five different locations in the coastal area after its functionality was verified through experiments. Based on the airborne chloride amount measured for one year, the distribution characteristics of airborne chlorides were examined by direction. In terms of direction, a large amount of airborne chlorides was collected, not only in the direction facing the coast but also in the opposite direction. The amount measured at effective three directions was 1.5 times that measured at non-effective three directions.
