수화열 제어에 의한 고강도 매스콘크리트의 자기수축 제어 = High Strength mass concrete by Hydration control of Autogenous Shrinkage Control

다국어 초록 (Multilingual Abstract)

In this study, to reduce the HHV of the high-strength mass concrete at early ages, PCM that could absorb the occurred hydration heat was applied, and the changes of autogenous shrinkage and the relationship between the hydration temperature and autogenous shrinkage were investigated. The addition of the The function of PCM could be worked below the original melting point due to the eutectic effect. While the hydration temperature and HHV of high-strength mass concrete can be decreased with the use of the PCM. A close relationship could be found between the hydration temperature and autogenous shrinkage; the higher the HHV, the higher the ASV and the greater the ultimate autogenous shrinkage.
