| Outline of Final Research Achievements |
In order to develop a rational concrete filling analysis method, the flow properties of fresh concrete were expressed in terms of rheological constants. In addition, a flow analysis method was developed that takes into account the flow during vibration and gap passage.
Furthermore, a visual material separation determination method based on machine learning and logistic regression was developed.

| Academic Significance and Societal Importance of the Research Achievements |
近年の鉄筋コンクリート構造物の施工条件および使用材料の多様化，過密配筋化と複雑な部材断面の増加，さらには労働者人口低下による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．従って，コンクリートの流動性を物理的に表し，合理的なコンクリートの充填解析法の確立を目標とした本研究は，学術的および社会的にも意義がある．
