Outline of Final Research Achievements |
The Accelerated testing method are proposed because it takes a very long time to discuss deterioration caused by penetration from the outside into concrete such as carbonation and chloride ion penetrate. The accelerated testing method have so far been established with concrete using Ordinary Portland Cement. On the other hand, considering the reduction of the environmental impacts, the use of mixed cement is also expanding. However, there are reports that the results of the accelerated test differ from the actual results. Therefore, in order to establish an optimum accelerated testing method, we obtained results which clarified the mechanism of material transfer.
