Corrosion Rates and Mechanical Properties of Rebar HRB400

Abstract:

The corrosion rates of rebar HRB400 in 0.5 wt.% NaCl solution were measured, and the mechanical properties before and 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 decreases at first and then increases.
