CORROSION-RESISTANCE OF STEEL FIBERS IN CONCRETE UNDER MARINE EXPOSURE

This is the final paper of a series which has reported different aspects of a long term study on the marine durability of steel fiber reinforced concrete (sfrc). Two mixes, one with and one without pfa were reinforced with three types of steel fibers. The cement content of the mixes was 430 and 590 kg/m**3 respectively. Prism specimens of these mixes were cured under marine exposure, both in the laboratory and at Aberdeen beach, for up to 200 wet-dry cycles (1200 days). The state of corrosion of the steel fibers was investigated visually and by electrochemical analysis of fibers. No corrosion of fibers embedded in concrete was evident.
