The corrosion rates of rebar HRB335 in 0.5%wt. NaCl solution and the tensile mechanical properties before and after corrosion of rebar were investigated. The results showed that, with increasing corrosion time from 30 days to 90 days, the corrosion rate of rebar HRB335 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.
