摘要：
The corrosion behavior of reinforcing bar HPB235 in simulated concrete pore solution (3.5 wt.% NaCl solution) was investigated, and the tensile mechanical properties before and after corrosion were tested. The results showed that, with corrosion time increasing from 240h to 720h, the corrosion rate increases and the corrosion becomes heavier. With the increase of corrosion time (corrosion rate), the yield strength and tensile strength decrease, but the elongation decreases at first and then increases.
