Kishi laboratory undertake research on (1) cement-based material resolving its
physical property, performance assessment, development and practical application
of new material and (2) quality inspection / maintenance of concrete structure.
Self-healing process of self-healing concrete Water flow reduction due to
generation of air bubble
◆ Development of simplified evaluation method of concrete surface quality
◆ Development of self-healing technology of concrete crack
◆ A study on mechanism of water flow reduction due to air bubble generation in crack
Application of self-healing concrete for water
leakage of underground infrastructures as tunnels
◆ A study on the relationship between micro pore structure and mass transfer in
cementitious material using micro/ nano technology
Evaluation of concrete surface quality
Surface air
