| Outline of Final Research Achievements |
In this study, for the purpose of developing a rational concrete filling analysis method, we investigated the prediction of freshness properties, the estimation method of rheological constants, and the estimation method of visual material separation judgment.
As a result of the examination, the prediction of fresh properties by machine learning is effective, the rheology constant is possible from the slump flow test, the visual material separation judgment can be estimated by the logistic regression analysis. Furthermore, the change in rheological constant under vibration could be examined.

| Academic Significance and Societal Importance of the Research Achievements |
近年，RC構造物の施工条件や使用材料の多様化，過密配筋化と複雑な部材断面の増加，さらには技術者不足の状況も相俟って，コンクリート工事を取り巻く環境は厳しくなっており，コンクリート工事の合理化は，建設業界において喫緊の課題である．そのような社会背景にあって，合理的なコンクリートの充填解析法の確立に向けた研究は，学術的には社会的にも意義がある．
