Experimental study on generation and development of interface corrosion between steel and concrete

Abstract

In this paper, generation and development of the interface corrosion between steel and concrete are investigated using the element test specimen which simulates the actual interface condition of the hybrid structures. The two types of element exposure tests are conducted, that is, the test focusing on the effect of the different environment of corrosion condition, and the test focusing on the effect of the bond between steel and concrete. Moreover, the effect of humidity on the interface neutralization and corrosion is investigated. As a result, the mechanism of generation and development of the interface corrosion between steel and concrete is predicted based on the experimental data.
