Investigation of Durability of Reinforced Concrete Member on Land Repaired by Electrodeposition Method

摘要

The purpose of this study is to investigate the durability of reinforced concrete member on land repaired by electrodeposition. In this study, there are two series of tests. In the first series, the reinforced concrete specimen after electrodeposition has been exposed outdoor for 2 years. Then, the durability of specimen after electrodeposition is investigated by measurement of the ratio of crack closure and the apparent coefficient of water permeability. Also, in the second series, the existing reinforced concrete member after electrodeposition has been left there for 2 years. Then, the durability of existing member after electro deposition is investigated by measurement of ratio of crack do sure, potential, polarization resistance, and carbonation depth. As a result, it can be derived that the repair effect of the electrodeposition method is maintained after the reinforced concrete repaired by electro deposition has been exposed for 2 years.
