Bond strength degradation in concrete cracked by expansion agent filled pipes

In this study, the bond behavior of corroded reinforced concrete was investigated by conducting pull-out tests on specimens with variable induced crack widths and different splitting modes. To simulate cracks due to corrosion focus their effect strength degradation, a novel method using expansion agent filled pipes is proposed. With increase width over elapsed time from filling aluminum pipe an agent, target obtained. The results confirm that type greatly influences reduction in deterioration more severe “Side-split” than “Single-split.” Furthermore, surface as variable, empirical formulas predict degradation rebar are These prediction models give good correlation when compared available literature.
