| Outline of Final Research Achievements |
In the Hokuriku district, a higher durability performance of infrastructures such as bridges and tunnels, which are newly constructed, is now required because the deterioration of concrete structures due to chloride attack and/or ASR becomes very sever and significant. On the other hand, in this district, at present, the production and quality control system of high-quality fly ashes is established, and the fly ash concrete is very superior to the durability against chloride attack and ASR. Based on the results of research work, the practical use of fly ash concrete for PC bridges and PCa products such as piles and concrete poles has been successfully carried out.
