Effect of Corrosion on Mechanical Properties of Reinforcing Bar HPB400

Abstract:

The corrosion behavior of reinforcing bar HRB400 in simulated concrete pore solution (3.5 wt. % NaCl solution) was studied, and the tensile mechanical properties after corrosion were tested. The results showed that, with corrosion time increasing from 240h to 720h, the corrosion rate of reinforcing bar HRB400 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.
