| Outline of Final Research Achievements |
In this research, we aimed to develop a method to determine curing plan so that hydration rate of cement can reach the target rate.
First, under various conditions, basic data on the effect of curing conditions on compressive strength development was acquired. Using the obtained data, hydration analysis was carried out and evaluated the influence of the curing condition on the hydration reaction of cement. As a result, we established a method for analytically predicting the influence of curing conditions on the hydration reaction of cement.Next, we have grasped the moisture condition at the time of performing various curing methods by experiments and established a method for predicting and predicting water supply and dissipation behavior during curing and after curing. Based on the above results, we proposed "a planning method for curing concrete structures based on cement hydration analysis". We also conducted case studies and verified the applicability of the proposed method.
