Corrosion Resistance Of Steel Fiber

An introduction to the corrosion resistance test of steel fiber concrete shows that when cracked steel fiber concrete components are exposed to moisture in a humid environment, the concrete at the cracks will carbonize, and the steel fibers in the carbonized area will rust. The depth of carbonization and the degree of corrosion will develop over time, and the impact on the steel fibers will increase. For concrete, the post-crack curvature and post-crack toughness are mainly used. Although the crack width is smaller than that of reinforced concrete, there are cracks after all. Therefore, anti-rust measures should be taken for steel fiber concrete used in humid environments, especially on the seaside. Measures. Tests have proven that, on the premise of ensuring that steel fiber concrete components have the same load-bearing capacity, using steel fibers with larger diameters can improve corrosion resistance. Using steel fibers coated with epoxy resin or galvanized can improve corrosion resistance. If the construction technology permits, this kind of steel fiber can be used only in the 1-2cm surface layer of the concrete. If necessary, stainless steel fiber can also be used.
