Corrosion Behavior of Rebar HPB235 in NaCl Solution

Abstract

The corrosion behavior of rebar HPB235 in 1.5wt.% NaCl solution was studied 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. After 720h, the yield strength, tensile strength and elongation are decreased by different extent.
