Corrosion Protection of Steel Structures

increase generates tensile stresses in the concrete, which fails along the bars. In a sound concrete the pH value of the cement paste is about 12-13, offering a protection to steel by the formation of a thin layer of bonded and insoluble oxide, which stops the reaction of oxidation. The corrosion is possible with a lower pH of
