CORROSION PROTECTION OF REINFORCING STEEL PROVIDED BY POLMER-IMREGNATED CONCRETE

The protection against corrosion provided reinforcing bars by polymer-impregnated concrete was investigated. Partially-impregnated slabs and fully-impregnated piling specimens were used in the investigation. The slabs were sprayed with salt water for 20 months and the pilings were immersed in sea water for 12 and 28 months. The bars from the control slabs had about 24 times more surface area corrosion than bars from the treated slabs. The chloride content in the treated slabs ranged from 4.6 percent to 38.2 percent of that in the control slabs. The bars from the control piles had corrosion ranging from 10 percent to 39 percent over the surface area while the PIC specimens had corrosion over 0.5 percent or less of the bar area. The chloride content of the PIC piles ranged from 3.4 percent to 8.5 percent of the chloride in the controls. /FHWA/
