ELECTRICALLY CONDUCTIVE POLYMER-CONCRETE OVERLAYS

The use of cathodic protection to prevent the corrosion of reinforcing steel in concrete structures has been well established. Application of a durable, skid-resistant electrically conductive polymer-concrete overlay would advance the use of cathodic protection in highway engineering. Laboratory studies indicate that electically conductive polymer-concrete overlays with conductive fillers, such as calcined coke breeze, in conjunction with polyester or vinyl ester resins have resistivities of 1 to 10 ohm-cm. Both multiple-layer and premixed mortar-type overlays have been made. Shear bond strengths of the conductive overlays to concrete substrates vary from 600 to 1,300 psi; the bond strengths of the premixed overlays are 50 to 100 percent higher than those of the multiple-layer overlays.
