Corrosion Time

The corrosion behavior of rebar HPB235 in 1.5wt.% NaCl solution was studied and its mechanical properties were tested before and after corrosion. The results showed that, with corrosion time increasing from 240h to 720h, the corrosion rate increases and the corrosion becomes heavier and heavier. After 720h, the yield strength, tensile strength and elongation are decreased by different extent.

Corrosion Time

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.

The corrosion behavior of reinforcing bar HPB235 in simulated concrete pore solution (3.5 wt.% NaCl solution) was investigated, and the tensile mechanical properties before and after corrosion were tested. The results showed that, with corrosion time increasing from 240h to 720h, the corrosion rate increases and the corrosion becomes heavier. With the increase of corrosion time (corrosion rate), the yield strength and tensile strength decrease, but the elongation decreases at first and then increases.

The corrosion behavior of rebar HRB335 in simulated concrete pore solution (3.5 wt.% NaCl solution) and the tensile mechanical properties before and after corrosion were investigated. The results showed that, with corrosion time increasing from 30 days to 90 days, the corrosion rate 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.

The corrosion behavior of reinforcing bar HRB400 in simulated concrete solution (0.5 wt.% NaCl solution) was investigated, and its tensile mechanical properties were tested before and after corrosion. The results show that, with the increase of corrosion time from 240h to 720h, the corrosion rate increases and the corrosion becomes heavier and heavier, and the composition amounts of corrosion scale are similar. After 720h, the yield strength and tensile strength are decreased by less than 10%, and the elongation are decreased by more than 20%.

The corrosion behavior of reinforcing steel bar HPB235 in concrete structure in 0.5% NaCl solution was investigated and its mechanical properties were tested before and after corrosion. The results showed that, with corrosion time increasing from 240h to 720h, the corrosion rate increases and the corrosion becomes heavier and heavier, but the corrosion scale is not changed obviously in compositions. After 720h, the yield strength is decreased by less than 5%, but the tensile strength and the elongation are decreased by more than 10%.
