| 摘要 |
The present invention relates to a cathodic protection system for reinforced concrete structures, having reinforced steel embedded in the concrete mix. The system includes an electrically conductive coating composition applied in fluid form over an outer surface of the concrete mix. The coating composition, when dry, comprises a permeable binder material through which moisture permeates preventing entrapment of moisture in the reinforced concrete structure. The composition further includes a predetermined amount of electrically conductive filler material uniformly distributed in the binder material whereby the coating composition has a predetermined value of resitivity. The coating composition protects the reinforced concrete structure from corrosion when electrical energy flows through the coating composition. The system further includes a source of DC electrical energy connective between the reinforcing steel and the electrically conducted coating composition such that the electrically conductive coating composition is anodic with respect to the reinforcing steel.
