The purpose of this study was to investigate the effect of finish surface coatings on the chloride attack resistibility of concrete. Recently, there has been studied for the amount of chloride penetration into concrete, but the actual construction has been built through of various finishing method except of exposed concrete. Therefore, this study was tested considering finishing materials while investigate the amount of chloride penetration into concrete. As a results of this study was obtained as follows, 1) This study identified amount by depth and distribution of Chloride Ion by using the Nernst-Planck equation. 2) There is chloride ion penetration quantity of none-coating concrete more then coating concrete. 3) The Chloride attack resistance of dry-bit is the best among the used materials. 4) This study identified fine structure of specimen and component analysis by using the SEM. 5) The influence factors of chloride ion migration coefficient are type, physical property and thickness of finishing materials.
