Research Themes

Durability of Concrete Structures

Durability of Concrete Structures In the Hokuriku District, steel corrosion and alkali-silica reaction (ASR) due to salt damage have become a significant problem with regard to the durability of concrete structures. As a Ministry of Land, Infrastructure, Transport and Tourism Bridge Doctor, Fukui Prefecture Bridge Life Extension Task Force Chair, and Ishikawa Prefecture ASR Task Force Chair, I address the problems of salt damage and maintenance of ASR-deteriorated bridges. The picture shows the cracked condition of a dam with ASR. The development of technology for inspection and diagnosis, and repair and reinforcement of such structures has become important.

Effective Utilization of Industrial By-products as a Material for Concrete

In the Hokuriku District, there are coal-fired power plants in Toyama, Ishikawa, and Fukui Prefectures, and the use of the large amount of coal ash (clinker ash, fly ash) that is generated by them as a construction material has become a problem. I have worked for many years on its use as a road material (subbase and filling material) and concrete mixture material with regard to its effective use as a construction material. The picture shows the exterior appearance of a concrete sample model. There are 36 similar models exposed on piers of Toyama New Port, and I examine age-related deterioration of fly ash containing concrete.

Strength Development of Ultra High-strength Concrete

Strength Development of Ultra High-strength Concrete High-strength concrete over 100MPa has become available as a construction material with the development of high-performance AE water-reducing agent and silica fume cement. I have been researching the microscopic structure and strength-developing mechanism of high-strength concrete, and aim to promote the use of concrete of both excellent strength and durability for long bridges and high-rise buildings. The picture shows the condition of emerging microscopic cracks of fluorescent resin paint impregnating concrete. I believe the mechanism of concrete deterioration can be explained through quantification of such cracks and spaces.

Utilization of Industrial By-products as a Concrete Material

Utilization of Industrial By-products as a Concrete Material There are coal-fired power plants operating in Toyoma, Ishikawa and Fukui prefectures in the Hokuriku District, and efficient use of the coal ash (clinker ash, fly ash) that is produced in those plants as construction material has been attracting attention from the perspective of local production for local consumption. As part of a research project conducted in collaboration with Hokuriku Electric Power, I study the durability of concrete mixed with fly ash. The picture shows the exterior view of test models exposed at Toyama New Port. I monitor age-related deterioration of the concrete test models by electrochemical measurement.
