The purpose of this study is to compare the strength according as variables of Hwang-Toe activation temperature based on existing references. Compressive strength tests were carried out when the activation temperature was set to 450℃, 600℃, 850℃ and the replacement ration was set to 30%, 50%. As a result, it showed that strengths of specimens overall increased to 850℃. However, strengths of specimens with 50% replacement of Hwang-Toe were significantly reduced at 450℃ and 600℃. In this regard, it is necessary to study the proper quality of activated Hwang-Toe for mortar application in the future.
