ABSTRACT
In general, the economic factor is one of the most influential in an engineering project. The economic cost of repairing the concrete structure, as well as the selection of a suitable protection system to protect the steel reinforcement from corrosion, is one of the major factors influencing the choice among various alternatives for repair or protection. Virtually every method has an expected lifetime. By knowing structure lifetime, one can easily calculate the number of expected maintenance projects to be done throughout that time. For a new structure, it is important to conduct an economic study to choose among alternatives for structure protection by considering the lifetime of the protection method with respect to the structure’s lifetime. In addition, it is necessary to take into account the initial costs of periodic maintenance.
