Abstract
The main idea of this study is to evaluate the bond strength for reinforcing concrete with corrosion that it can damage the R.C bond. Pullout tests carried out to evaluate the effects of corrosion on bond, for that purpose a series of specimens with varying reinforcement corrosion levels tested. The acceleration steel corrosion was 4, 6 and 8 days corrosion. The aim of choosing 4, 6 and 8 days that are trying to reflect field condition on test. The test designed to provide the data required to assess the bond properties with different variables, bar diameter and concrete strength. The pullout test specimen was designed to can get best significant result by provided anchored length and avoid yield failure. The test result shows verity relation between the bond strength and corrosion. The percentage of steel metal loss was smaller for a large diameter bar compared to that for smaller diameter bar at a constant corrosion rate. For C30-10 results show there are reduction with bond strength around 22% for 4 days corrosion, 25% for 6 days corrosion and 31% for eight days corrosion. While for C30-14 results show there are reduction with bond strength around 19% for 4 days corrosion, 23% for 6 days corrosion and 28% for 8 days corrosion.
