Corrosion Behavior of Reinforcing Steel Bar HPB235 in NaCl Solution

Abstract:

Article Preview

The corrosion behavior of reinforcing steel bar HPB235 in concrete structure in 0.5% NaCl solution was investigated and its mechanical properties were tested before and after corrosion. The results showed that, with corrosion time increasing from 240h to 720h, the corrosion rate increases and the corrosion becomes heavier and heavier, but the corrosion scale is not changed obviously in compositions. After 720h, the yield strength is decreased by less than 5%, but the tensile strength and the elongation are decreased by more than 10%.
