| Outline of Final Research Achievements |
Sometimes cracks are used as an index of deterioration grade. For this reason, crack opening weight loss or relationship between crack width and weight loss have been studied by many researchers. Recently, however, it is reported that not only cover thickness or bar diameter which have been thought to be main factor for crack opening but also corrosion products may have large influence. However, formation process of corrosion products in concrete is still unclear and it is difficult to predict corrosion products formed in concrete constructed in various environment.
Then in this study, in order to arrange formation process of steel corrosion products in concrete, XRD analysis of steel corrosion products formed under various corrosion environment was carried out. Additionally, influence of corrosion products on relationship between crack width and corrosion weight loss was investigated.
