- 2011-2013年度科学研究費助成事業（基盤研究（A））研究成果報告書 課題番号：23246081 研究代表者：武若耕司（鹿児島大学・理工学研究科・教授）けい酸塩系表面含浸材の特徴は、コンクリート上層部を改質することで劣化因子の侵入を抑制させるもので、施工の容易さと経済性から利用が急増している。しかし、この材料の効果に関する研究は少なく、コンクリート表層部の改質範囲や性能改善の定量評価は未だ不十分である。本研究では、けい酸塩系表面含浸材の効果を定量的に評価し、既存構造物の長寿命化対策として有効に活用するための補修設計方法および施工管理方法に対する提言を行った。なお、本研究に対する主な成果は、土木学会から発刊された「けい酸塩系表面含浸工法の設計施工指針（案）」に盛り込まれている。Silicate-based Surface Penetrant, which improves mechanical properties of surface concrete and provides resistivity against ingress of harmful substances, is increasingly being applied to concrete structures. However, its penetration property and improved condition of the penetrated portion, which must be important factors to estimate the long-time performance of applied concrete structure, has not been clear quantitatively yet. In this study, by evaluating its effectiveness on concrete surface quantitatively, new guideline for design and construction methods to use Silicate-based Surface Penetrant has been proposed.
