| Outline of Final Research Achievements |
We proposed a curing planning method that makes a rational curing plan based on the hydration analysis of cement. The purpose of this study was to improve the degree of perfection and practicality of the proposed planning method for curing, and to promote its social implementation. As a result, the following results were obtained. (1) The applicability of the proposed method to various curing methods was expanded. (2) The applicability of the proposed method to various types of cement was expanded. (3) We developed a curing planning method that considers both productivity and low carbonization and securing performance by curing. Based on the above results, we have completed a curing planning program that can calculate the required curing period according to various conditions, and a highly complete curing planning support program that can consider both low carbonization and productivity.

| Academic Significance and Societal Importance of the Research Achievements |
研究成果により、各種養生工法および各種セメントを用いた時の必要養生期間を合理的に求めることができ、費用対効果を考慮した合理的で確実な養生計画の立案が可能となる。また、各種条件から必要養生期間を容易に算定可能な養生計画立案支援プログラムの提供により社会実装が推進され、所要の性能を有するコンクリート構造物の構築に繋げることができる。さらに、生産性あるいは低炭素化と養生による性能確保の両立を考慮した養生計画立案手法の開発により、コンクリート工の生産性の向上、低炭素型セメントの利用拡大による炭素排出量の低減など、各種課題解決に大きく貢献できる。以上より、研究成果の学術的意義および社会的意義は大きい。
