MARINE CURING OF STEEL FIBER COMPOSITES

A study is reported which compared the effects of normal and sea water curing on the long term pull-out behavior of steel fibers embedded in cementitious matrices. The effects of silica fume addition and temperature of curing on the durability of a single fiber unit were also studied. It was found, based on a limited number of tests, that the marine curing of steel fiber concrete appears to be acceptable only at very low (less than 2 deg C) ambient temperatures. High temperatures promote early corrosion and lead to strength reductions. The silica fume does not appear to ehance corrosion. Preferential anodic pitting is possible at the deformed locations in the fibers, perhaps due to residual stresses. This finding is relevant in the manufacture of fibers for marine applications
