Mechanical Properties of Rebar HRB400 after Corrosion

Abstract

The corrosion behavior of rebar HRB400 in 3.5 wt.% NaCl solution was investigated, and the tensile mechanical properties after corrosion were tested. The results showed that, with the increase of corrosion time, the corrosion rate of rebar HRB400 increases and the corrosion becomes heavier. Meanwhile, the yield strength and tensile strength decrease, but the elongation increases at first and then decreases.
