Zusammenfassung:The anticorrosion performance and field application of a new rebar inhibitor were evaluated through the tests of half-cell potential and weight loss. The results indicated that half-cell potential of rebar had a negative shift with the addition of chloride ion, so it took long time to reach the stable potential. With the increase of chloride ion in the system, half-cell potential was more difficult to achieve stability. When chlorine ion content was low, inhibition effect was very obvious. Inhibition efficiency was 85.53% without chlorine ion and 85.74% with 1.0%NaCl by weight loss. New Rebar Inhibitor had no effect on the mechanical properties of concrete, which had good protective effect on concrete pipe rack in using.
