Current Research Overview

My research is currently structured around two primary pillars:

1. Development of Value-Added Products Utilizing Industrial By-products and Untapped Resources This research focuses on the effective utilization of waste materials such as discarded glass fiber reinforced plastics (GFRP), silica gel, and glass cullet to develop porous ceramics and geopolymers. Additionally, volcanic pyroclastic materials—including pumice and shirasu—are being explored as raw materials for concrete products. The ultimate goal is to implement these materials in practical applications within society.

Rather than merely blending these by-products into conventional formulations, the research emphasizes maximizing the inherent properties of each raw material. This approach aims to enhance the functional performance and sustainability of the final products, contributing to circular economy principles and resource efficiency.

2. Maintenance and Management of Civil and Architectural Structures This research aims to improve the durability and self-sustainability of concrete structures. One key focus is the development of self-healing concrete by incorporating microcapsules—approximately 200 µm in diameter—containing restorative agents. These capsules are designed to rupture upon structural degradation, thereby releasing the agents to autonomously repair cracks.

In parallel, deep learning techniques are being applied to analyze crack images in concrete structures. The objective is to achieve detection accuracy comparable to that of manual visual inspections, thereby enhancing the efficiency and reliability of structural health monitoring systems.

研究内容

現在，2本の柱で研究しています．

1本目は，産業副産物や未利用資源を有効利用した付加価値のある製品開発です．廃GFRP，廃シリカゲル，及び廃ガラスカレットを原料とした多孔質セラミックスやジオポリマー，また火山砕屑物（軽石，シラス）を原料としたコンクリート製品の社会実装を目指しています．これら製品は，単に副産物を混ぜるのではなく，原料の持つ特徴をできるだけ活かすことに注力しています．

2本目は，土木・建築構造物の維持管理に関する研究です． 直径200 µⅿ程度の薬剤を内包したカプセルをコンクリートに混合し，劣化が生じた際に自己修復機能を有する構造物を目指しています．また構造物のひび割れ画像を深層学習で解析し，目視点検と同等精度で検出することを目指しています．
