       Strategy

The basis of research activities in our concrete laboratory is to contribute to society and earth resources as concrete has been utilized as a fundamental construction material. In addition, our concrete laboratory is beginning to widen areas like microbe decomposition by applying acquired knowledge from the past researches.

Our research approach does not separate between material and structural aspects, but develop the integrated material& structural concrete engineering system. The application is applied to life cycle management & assessment, the verification& evaluation system for safety and durability of a structure including seismic performance.

Now, the application is extending to simulation of the pore structure within soil material and cementitious materials, prediction of thermodynamics states, material transport of cementitious materials and soil material, and the diffusion problem.

Furthermore, the technology accumulated by years of our research for concrete is also applied to the reaction decomposition system of a microbe. It is expected that an optimization in design of an organic waste disposal facility and improvement in the speed and the efficiency of processing will be achieved by the simulation of compost process.

  Contribution

Publication of Specification and Guideline

 Laboratory staffs attend to publication and revision of several kinds of specifications or guidelines. For a part of them, we play the key role as a chairperson or secretary. Check the website of JSCE or JCI etc. for details. According to research progress, publications and lectures are carried out by teachers any time.

Product of Research Fruit ~ Self Compacting Concrete 

 "Self Compacting Concrete (SCC)" originated in a laboratory at the University of Tokyo.  It is developed by prof.Okamura, prof.Maekawa, prof.Ozawa two decades ago. This innovative material can through complicate mesh of reinforcement bars and fill formworks  by itself without any compaction and segregation. Also hardened material shows high strength and high durability because of it's density. The SCC always ensure high quality of concrete structure.

Product of Research Fruit  ~ Numerical Simulation Program

 A part of accumulated research fruit in a past decade is numerically programmed, and it is produced as software. To give actual examples, there are RC structural response analysis tool WCOMD (2D analysis) and COM3 (3D analysis), concrete material behavior analysis tool DuCOM and so on. 

Business Production on a Commercial Basis by Graduates

 In order to smoothly and quickly connect the laboratory with the public, and to promote practical use and technology transfer of fruits of research and technical development, a new company (COMS Engineering corporation and DuCOMs corporation) is established by graduates. Not only Software sales or publication but also technical support of structural analysis are undertaken there.
