In this study the effect of corrosion on time dependent bond behavior was investigated experimentally. Reinforced concrete prism specimens were made of concrete with 0.60 water cement ratio (w/c) and were provided with two separate reinforcement steel bars arranged along their longitudinal axis. One of the steel bars with shorter embedded length was corroded electrolytically before performing pull out test. Bond stress level was chosen as a major facter for a corrsion of 5.5% percentage of mass loss. The results show that if bond stress level exceeds 62%, remarkable creep of bond takes place. Moreover, load history may have some effect on slip creep in presence of corrosion. |
