In this study, the same mortar chip specimens were exposed to estimate airborne salt environment in 101 places in Japan.
The conversions of the chloride content of the specimen into the surface chloride concentration were carried out. The revised distance was calculated using the distance between specimen and shoreline, the altitude of specimen, the wind direction and the wave energy of exposure test place.
From the regression analysis, the estimation method of the surface chloride concentration of the concrete at various environment using the revised distance was formulated.
