ABSTRACT
This paper deals with a proposal of a practical repair strategy, using nitrite corrosion inhibitor, for salt-damaged reinforced concrete structures based on experimental studies. The conventional repair system, in which cover concrete is removed and the profile is restored at the severely deteriorated parts and only the concrete surfaces are repaired at other parts, may result in accelerated rebar corrosion due to macrocell action. By the proposed repair system, however, the same treatment as the conventional one is conducted at the severely deteriorated parts, but the low-pressure injection and the impregnation of the corrosion inhibitor are conducted where the cracking is slight and no cracking is found, respectively. This system extends the service life of structures.
