Introduces a typical repair case of chemically attacked reinforced concrete structure. At the present time, the maintenance of reinforced concrete structures is a common and a serious problem for industry in Korea. The structure examined is in a chemical plant that processes sulfates. The repair procedures are described by the following five basic steps: 1) how to find the deterioration, 2) how to determine the causes of deterioration, 3) how to evaluate the strength of the existing structure, 4) how to decide the repair needed, and 5) what kind of repair method and material should be selected. This paper also suggests the future research direction of repair techniques of reinforced concrete structures in Korea
