Abstract
When the concrete is subjected to chloride attack or carbonation, the passive steel normally initiate corrosion. By product of corrosion make volume of concrete expand 3 to 8 times and induce the stress which lead cracking and spalling of concrete. It result in the loss of the integrity of the concrete structures. Several corrosion inhibitors imported from America, Japan and Europe are currently being used to repair the concrete structures in Korea. However, questions has been raised for protective effect of the corrosion inhibitors which applied in steel reinforced concrete structures. Therefore, we investigated the influence of type and amount of corrosion inhibitors through the tests immersing in salty water. In addition, we developed the corrosion inhibitive agent treating to surface of concrete structures for improving resistance to penetration and corrosion of the steel reinforcement.
