- Abstract
- 본 연구에서는 동결융해 환경에서의 제설제 노출 조건에 따른 보통포틀랜드시멘트 콘크리트의 동결융해 저항성을 평가하였다. 300 사이클의 촉진동결융해 환경에 노출된 콘크리트의 상대동탄성계수, 중량감소, 압축강도에 대하여 변화를 측정하여 동결융해 저항성으로 판단하였다. 그 결과, 제설제의 종류에 따라 단일물질로 구성되어있는 것을 사용하였을 때 콘크리트의 동결융해 저항성이 높게 나타났다.
In this study, freeze-thaw resistvity of ordinary Portland cement concrete was evaluated under different deicing salt exposure. The freeze-thaw resistvity was identified by measuring change of relative dynamic modulus of elasticity (RDME), weight loss and compressive strength after 300 cycles of freeze-thaw condition. Depending on cation type, freeze-thaw resistvity was varied and with unifrom substance was after to make better freeze-thaw resistvity.
