- Abstract
- 본 연구에서는 동결융해 환경에서의 제설제 노출 조건에 따른 보통포틀랜드시멘트 콘크리트의 내구수명을 부식저항과 동결융해저항에 대한 측면으로 나누어 예측하고 이를 바탕으로 콘크리트 수명에 적합한 제설제 종류를 제시하였다. 300 사이클의 촉진동결융해 환경에 노출된 콘크리트의 염분침투속도를 측정하여 부식저항 내구수명을 산정하였고 상대동탄성계수를 측정하여 동결융해 저항 내구수명을 산출하였다.
In this study, service-life of ordinary Portland cement was estimated in terms of corrosion resistivity to suggest appropriate deicing salt type to concrete service-life. The service-life of concrete against corrosion was estimated by measuring diffusion coefficient and the service-life concrete against freeze-thaw was estimated by change of relative dynamic modulus of elasticity(RDME) after 300 cycles of freez- thaw condition.
