Abstract：The corrosion inhibiting behavior and the change of concrete properties after the addition ofa new rebar corrosion inhibitor DETA-TU were studied by EIS method. The results show that the re-sistance of both concrete pore solution and the charge transfer of rebar corrosion process are increased.It has been proved that DETA-TU is a dual function corrosion inhibitor, namely, it can cut out part ofthe capillary in the concrete as well as build up a protective layer on the rebar surface. The results afterlong period immersion show DETA-TU has a good water resistance. Compared with nitrite, DETA-TU has a different corrosion inhibiting mechanism.
