Apr 14, 2017 · Therefore, the key solution to avoid corrosion problems is to enhance the passivity and anti‑chloride-corrosion ability of steel rebar [1,2]. In general, coated steel rebar is the main corrosion improvement method, such as epoxy‑coated steel rebar and alloyed steel rebar [3,4,5]. Coated steel rebar has been developed for decades. Corrosion-Resistant Reinforcing Steel Effective corrosion resistance is the product of appropriate design and material selection for conditions as well as responsible field handling. Steel is manufactured by heating iron ores that are primarily iron oxides along with other ingredients. ….
