Outline of Final Research Achievements

In order to realize super long service life of more than 100 to 1000 years, we develop a new type of self-repairing concrete based composite material and structural systems. In the present self-repairing concrete, the cracks can be automatically or very easily repaired. We perform a number of experiments of the proposed composite material and structural systems to study the repairing capability, constructability, and structural performance. From the experimental results, we make chemical and mechanical models and prepare fundamental data necessary for material and structural design.
