About the Lab

전남대학교 건축학부 건설재료 연구실에 오신 것을 환영합니다.
We develop next-generation high-performance fiber-reinforced cementitious composites, self-healing materials, and AI-assisted construction materials, with a focus on sustainability and resilience.

Our flagship achievement: concrete that can stretch up to 22 % tensile strain — bending far beyond steel — enabling rebar-free resilient infrastructure.

Research Areas

🧱 High-Ductility Composites

ECC, UHPC, and alkali-activated cement-free composites achieving tensile strain capacities up to 22 %.

🔄 Self-Healing Materials

Crack self-healing in slag-based and ECC composites — reducing lifecycle maintenance costs.

📊 AI & Image Processing

Neural networks and image processing for fiber distribution evaluation, crack measurement, and mix optimization.

🔇 High-Damping Materials

Polyurethane-based composite systems for vibration and seismic energy absorption.

💎 Light-Transmitting Concrete

Innovative architectural concrete that transmits natural light through embedded fiber optics.

🌿 Sustainable Concrete

Low-CO₂ cementless geopolymer composites and recycled-fiber-reinforced materials for green construction.
