The authors propose a method to formulate a curing plan to achieve the target hydration rate to ensure the required performance. In recent years, cases of applying low heat type cement to general reinforced concrete structures for the purpose of crack reduction are also increasing. Although these low-heat type cements need to be subjected to wet curing for a longer period of time, the concrete standard does not indicate the standard of wet curing period.In this research, the applicability of the analysis program to low heat cement is confirmed using experimental data from previous research, and We tried to determine the required curing durarion when low heat type cement is used.
