- Description
- Chloride penetration is the main cause of corrosion in reinforced concrete (RC) structures located in marine environments. The deterioration could possibly cause severe cracking at concrete surfaces. This study investigates the effect of reinforcement confinement (including transverse reinforcement) and spacing of reinforcing bars on concrete cover cracking using accelerated corrosion tests. These tests have become the most satisfactory method used in the laboratory to accelerate and simulate the corrosion process. The accelerated corrosion test adopts an electrochemical technique, which involves the application of alternating current. In this study, corrosion was induced along the deformed bars by adding calcium chloride into a concrete mixture. The experiment concentrated only on reinforcement confinement and spacing of reinforcing bars to measure corrosion-induced crack width and rate of crack propagation. Results revealed that confinement and spacing of reinforcing bars have a significant effect on the rate of crack propagation.
