Currently, there is no local standard on reinforced concrete structures repairing in Malaysia. The aim of this study is to discuss the similarities and differences of the reinforced concrete structure repair codes of Australia, Eurocode, and United States.In the methodology and work plan stage, preliminary decision for concrete repair is made after the structural assessment. Next, repair work is conducted in relation to the general planning. Lastly, repair products applied in the system are ensured to be mutually compatible in order to accept the repair work. According to the 11 principles listed in EN 1504-9, concrete damages are classified as concrete defects and corrosion on reinforced concrete structure. SA HB 84:2018 is using the fundamental principles of EN 1504 as the main reference. Similarly, all three codes highlight the reinforcement corrosion as the primary reason of concrete damage. The main difference between ACI 546R-14 and EN 1504 is ACI 546R-14 provides no principle for all intended uses in repair works. Two case studies of reinforced concrete structure repairing for irrigation control structures and low-cost flat building are discussed. The case studies reveal a possibility of combining the strengths of a selected standards in reinforced concrete structures repair works.
