- Synopsis
- By corroding steel in solution for the verification from a thermodynamic viewpoint, protection performance to steel materials of a hardened cement is clarified. The mole ratio of the amount of chloride ion (corrosion factor) and the amount of hydroxide ion (protection factor) presumes the maximum amount of chloride ion due to verify the recent research results affects steel corrosion. Furthermore, the consideration about the maximum value of the amount of chloride ion in PC grout is verified from the mole ratio.
