Abstract This study has tested and empirically analyzed the properties of the high quality recycled fine aggregate produced by wet gravity separation system using waste concrete. The result of this study may be used as a basic date for adding higher values to the recycled fine aggregate to be used in concrete. The summary of this study's result is as follows. In terms of the changes in the resistance to chemical attacks, the concrete using 100% of natural fine aggregate showed greater resistance but the difference was insignificant. It can be understood that the replacement ratio and the type of aggregate rarely effect on the resistance. Alkali potential reaction was tested through the mortar-bar method (KS F 2546), all of them met the KS standards.
