Effects of Pore Structure of Ground Granulated Blast-Furnace Slag Concrete on Freezing-Thawing Resistance

고로슬래그 미분말 콘크리트의 공극구조가 동결융해 저항성능에 미치는 영향

In this study, effects of pore structure of ground granulated blast-furnace slag concrete on freezing-thawing resistance are reviewed. As a result, degradation of freezing-thawing resistance performance was occurred as replacement ratio of ground granulated blast-furnace slag increases under same specified concrete strength condition. It is considered that pore structure of internal binder affects freezing-thawing resistance performance.
