| Research Abstract |
In order to utilize and maintain the existing concrete structures for long period of time, it is important to evaluate the performance of the structure and take appropriate countermeasures. To deal with the problem, “redesign method” was studied to get the detailed information of old existing structures without any design documents left. The results show that the details of the old existing structure can be estimated by utilizing both “redesign method” and non-destructive inspections with enough accuracy. Also, to determine the deterioration of the structure, chemical analyses were performed on hydrates of the used cement containing different types of mineral admixtures. The changes of the hydrates after the penetration of harmful ions were investigated and the mechanism of the changes were clarified which can be used to estimate the cause and degree of deterioration by non-destructive inspection
