摘要

This study evaluated the corrosion resistance and plastic shrinkage control properties of amorphous metallic fiber used to reinforce cement composites. Amorphous metallic fibers, based on amorphous metals, are typically thin and are believed to be highly corrosion resistant. After exposing amorphous metallic fibers to five different types of degradation environments for 30, 60, and 90 days, a tensile test was conducted to evaluate corrosion resistance and reduction in tensile strength. Also, a plastic shrinkage crack test of amorphous metallic-fiber-reinforced cement composite was carried out, and comparisons were made with conventional steel-, polypropylene-, and polyvinyl-alcohol-fiber-reinforced cement composites. Test results show that amorphous metallic fibers displayed higher corrosion resistance than did steel in every degradation environment, and plastic shrinkage crack control performance was excellent.
