Hydrate Heat Analysis for the Determination of Optimized Thickness in Mass Concrete

매스 콘크리트의 적정 타설높이 산정을 위한 수화열 해석

The thermal crack in mass concrete is mainly due to the difference of concrete temperature, which is generated by hydration heat of cement. As the thickness of mat foundation increases, the difference of temperature becomes bigger. The purpose of this study is to estimate the optimum placing depth. The temperature of real mat foundation was observed and the thermal analysis by Finite Element Method was executed. Finally, the crack index according to the placing depth was estimated.
