Study on Mechanical Properties of Rebar HRB400 after Corrosion

Abstract:

The corrosion behavior of rebar HRB400 in 1.5 wt.% NaCl solution was studied, and the mechanical properties before and after corrosion were tested. The results showed that, with the increase of corrosion time from 240h to 720h, the corrosion rate of rebar HRB400 increases and the corrosion becomes heavier. Meanwhile, the yield strength and tensile strength decrease, but the elongation decreases at first and then increases.
