The quantification of the influence of environmental effects that is deterioration is indispensable to do prediction of the deterioration progress of a concrete structure due to the salt damage.
The lamina mortar test piece was done with a wind tunnel type coming flying salinity environment reproduction device ideally controlled and the reproduction experiment of the process that the salinity that adhered to [**] doing and the surface infiltrates the coming flying salinity was done. And, it was tried to express this process by the numerical analysis. Moreover, the effect of the salinity removal of washing the surface of concrete where the coming flying salinity adhered by high-pressure water by using this testing set was additionally examined.
As a result, the infiltration's of salinity to the inside continuing afterwards became experimentally clear though the volume of salt on the mortar surface would reach the condition of equilibrium for a certain period when the coming flying salinity was continuously supplied. Moreover, the amount to the inside of the salinity infiltration decreasing became clear as for concrete that gave washing with the high-pressure washing device.
