Saito-Yoshioka Lab
Machine-translated · View original
The lab studies building materials such as concrete, along with the fire safety of buildings.

AboutAbout the lab
Eco-friendly materials and fire-resistant buildings.
The Saito-Yoshioka Lab studies building materials that contribute to resource circulation and carbon neutrality, as well as the safety of buildings against fire.
In the materials area, the lab designs building materials based on chemistry, and works on capturing and storing CO2 in cement and concrete and on developing "recycled cement."
In the building fire safety area, the lab studies how fire spreads over exterior walls, the toxicity of gases produced in fires, and how fire spreads through urban areas.
Together with the Noguchi Lab and the Maruyama Lab, the lab operates as the "Building Materials Lab (BME Lab)."
Key terms
- Resource circulation
- Reusing materials as resources again after use, instead of discarding them
- CCUS
- A general term for technologies that capture carbon dioxide and either use it in manufacturing or store it underground or within materials (carbon capture, utilization and storage)
- Calcined clay
- Clay that has been fired at high temperature. It is used as a material combined with cement
- Building fire safety
- The engineering field of making buildings in which fires are unlikely to start, do not spread even if they do, and from which people can escape safely
NewsLab news
Professor Maruyama, Assistant Professor Ryo Kurihara, and colleagues published a method for measuring the amount of CO2 fixation using carbon isotope ratios
Associate Professor Hideki Yoshioka received the Faculty of Engineering Best Teaching Award
Assistant Professor Ryo Kurihara and colleagues received the Cement Association of Japan Paper Award
Held a lab introduction session for third-year undergraduates; recording and materials are now available
Held an information session on assignment to labs for graduation theses; materials are now available
ResearchResearch themes
The lab designs and creates building materials, grounded in chemistry, that contribute to resource circulation and carbon neutrality. In building fire safety, it studies how materials and building components burn, the toxicity of gases produced in fires, and urban fires.
*Illustrative imageEvaluating fire protection and fire resistance performance
The lab studies how fire spreads over combustible exterior walls and countermeasures against it, the evaluation of the toxicity of gases produced in fires and its application to safe evacuation design, and the prediction of how urban fires spread during major earthquakes and strong winds.
*Illustrative imageCapturing and storing CO2 in concrete
The lab studies methods that use cement and concrete materials to capture carbon dioxide and then utilize or store it (CCUS).
*Illustrative imageDeveloping "recycled cement"
The lab studies "recycled cement," covering both the design of the material itself and the development of a system for producing and using it.
*Illustrative imageCement-based materials using calcined clay
The lab designs new cement-based materials using calcined clay, which is clay that has been fired at high temperature.
