상전이물질을 사용한 매스콘크리트의 수화열 특성 = Hydration Heat Characteristics of Mass Concrete Using Phase Change Material

국문 초록 (Abstract)

상전이물질(PCM)의 활용은 매스콘크리트의 수화열을 줄일 수 있는 효과적인 방법 중의 하나이며 최근 상전이물질을 이용한 콘크리트 복합체에 대해 연구가 진행되고 있다. 본 연구에서는 PCM 혼입 및 저발열 결합재의 사용에 따른 매스콘크리트의 열적특성을 평가하였으며, 실제 구조물에 대한 수화열해석 및 현장시공 적용을 통한 검증을 실시하였다. 실험 결과 수화열 해석에 의한 값이 실제구조물의 수화발열 및 온도 상승이력에서 유사한 경향을 나타내므로 수화열 온도이력을 검토하기 위해 수화열 해석 프로그램의 활용이 효율적인 방법이라 판단된다. 또한 저발열 결합재와 PCM 혼입이 매스콘크리트의 수화열 저감 및 온도균열 감소에 효과적인 것으로 판단된다.

One of the effective techniques to mitigate thermal stress in the mass concrete is to use the phase change material(PCM). In recent years, many researchers have conducted studies on the PCM concrete composite. The main objective of this study was the influence of PCM on hydration heat of mass concrete with ternary blended cement. To verity the accuracy and computation efficiency of simulation analysis, compared to measurement data from actual structure. The simulation analysis results indicate that the temperatures determined by the analysis are in good agreement with the measured values from actual structure. The simulation analysis of finite element procedure is feasible as an auxiliary method of temperature management. It was observe that the incorporation of PCM in mass concrete leads to a decrease of the maximum temperature and reduction of thermal crack. Therefore, the incorporation of PCM with ternary blended cement is effective in controling the hydration heat of mass concrete.
