Areas of specialization History of rail transport
Laboratory/research office Concrete Laboratory
Investigating on concrete technology for the enhancement of the reliability of concrete structures. Developed Air-enhanced Self-Compacting Concrete (air-SCC) first in the world, by making use of micro bubbles for attaining self-compactability of fresh concrete economically. Also, investigating for getting concrete on the material circulation.
