The authors propose a method to formulate a curing plan to achieve the target hydration rate to ensure the required performance. In applying this method to various curing methods, it is necessary to appropriately set the boundary conditions according to the water supply and retention performance of the curing method. In this study, to obtain the basic data necessary for setting the boundary conditions, the water supply and retention performance was measured by measuring the mass change of the specimens cured by various curing methods. In addition, the performance of concrete was evaluated by non-destructive tests in order to understand the curing effect of various curing methods.
