This study analyzed the temperature rise and thermal cracking in the nuclear containment structures owing to the hydration heat of cementitious materials. The main parameters investigated were the one-layer casting height of concrete to examine the shortening of construction time of the structures. The current mixture proportions of concrete needs to be modified to increase the one-layer height of concrete, minimizing the likelihood of the occurrence of thermal cracks.
