Effect of Chloride on Corrosion Behavior of Reinforcing Steel HRB335

Abstract:

The corrosion behavior of reinforcing steel HRB335 in structure in simulated concrete solution (0.5 wt.% NaCl solution) was investigated, and its tensile mechanical properties were tested before and after corrosion. The results show that, with the increase of corrosion time from 240h to 720h, the corrosion rate increases and the corrosion becomes heavier and heavier, and the composition amounts of corrosion scale are not familiar. After 720h, the yield strength is decreased by about 3%, and the tensile strength and the elongation are decreased by more than 4%.
