Airborne chlorides is moved to inland by sea wind and attach to the surface of concrete then penetrated into concrete. In addition, concrete structures are greatly affected by salt attack primarily due to airborne chlorides like it can be seen through the corrosion of rebar. Therefore, it is important to review the relationship among airborne, surface and penetrated chlorides. In this study, airborne, surface and penetrated chlorides were examined in terms of surface roughness of concrete. The results showed that penetrated and surface chlorides have close relationship with surface roughness of concrete.
