Areas of specialization	Railway network planning
Laboratory/research office	Concrete Laboratory Our laboratory is working to develop refined concrete technology for the enhancement of the reliability of concrete structures. We have developed Air-enhanced Self-Compacting Concrete (air-SCC), a world first, through the application of micro bubbles to achieve economical self-compactability of fresh concrete. At the same time, we are investigating the application of this method to other materials.
