Effect of Corrosion on Mechanical Properties of Rebar HRB335

摘要

The corrosion behavior of rebar HRB335 in simulated concrete pore solution (3.5 wt.% NaCl solution) and the tensile mechanical properties before and after corrosion were investigated. The results showed that, with corrosion time increasing from 30 days to 90 days, the corrosion rate increases. With the increase of corrosion time (corrosion rate), the yield strength and tensile strength decrease, but the elongation decreases at first and then increases.
