Abstract
Concrete structures have played an important role in the improvement of the social matrix so far. Therefore, the deterioration of concrete structures at relatively early stages found during their use has become a serious social problem. The main causes are cracking, neutralization, corrosion of rebar, etc. Investigation for the prevention and protection against the deterioration of concrete structures has been done both from the viewpoints of economics and safety. In this study, we investigated and assessed the corrosion characteristics of galvanizing steel in concrete solutions to establish countermeasures for corrosion prevention of steel rebar. As a result, we obtained the results that zinc reacted with solutions containing chlorides of higher concentration and that the corrosion characteristics for zinc film containing aluminum decreased.
