A lab that focuses on concrete structures and works to extend the service life of social infrastructure.

AboutAbout the lab
Supporting social infrastructure through concrete structures.
The Concrete Lab focuses on concrete structures and carries out research and education that contribute to making social infrastructure in Japan and abroad more resilient, more durable, and longer-lived.
Its work ranges widely, from research and technology development on materials and structures to reform of social systems, covering not only academic research but also practical research.
The lab actively collaborates with companies and operators, and also aims to put its research results into practice in society.
The lab's website introduces it under the name "Concrete Lab."
Key terms
- Strengthening resilience
- Making a structure stronger against external forces and less likely to break
- Extending service life
- Making it possible to keep using a structure for a long time
- Social implementation
- Making the results obtained from research usable in actual society

ResearchResearch themes
This lab runs research projects that consider social infrastructure as a whole, centered on concrete structures and spanning materials, structures, urban disaster prevention, and construction management. It collaborates with companies and operators, and also aims to put its research results into practice in society.
*Illustrative imageDurable Concrete Structures
The lab conducts practical research on social systems, inspection technologies, and material development to ensure the durability of concrete structures.
*Illustrative imageExploring the Ideal State of Social Infrastructure
From the perspective of urban disaster prevention, the lab views infrastructure as a network and conducts research aimed at making social systems more resilient. It also carries out research and development that contributes to extending the service life of concrete structures, which play a central role in infrastructure.
